Speaking at the Consumer Electronics Show, AT&T executive Ralph de la Vega said that the company plans to release 20 4G devices this year both for the LTE network and for its current HSPA+ network.

De La Vega said just after that that the company will have devices on the Apple, Android, BlackBerry and Windows Phone 7 operating systems. (Update: 12:12 p.m.: While some in the audience, including Mobilized, heard an implication that there would be a 4G iPhone, an AT&T representative said De La Vega was only saying that the iPhone would be part of AT&T’s smartphone lineup and not suggesting a 4G version.)

Among the devices that will be on AT&T’s HSPA+ network is the Motorola Atrix 4G, a dual-core-powered Android phone from Motorola. The phone, which also packs 1GB of RAM, was launched by Sanjay Jha, CEO of newly split-off Motorola Mobility. one of the more interesting features is the phone’s optional “lap dock,” which allows the phone to power a small laptop capable of running a desktop version of the Firefox browser, among other programs.

AT&T will also have a new phone from HTC that will include a new version of the company’s Sense user interface and also connect to a new HTCSense.com Web portal.

“HTCSense.com makes your smartphone even smarter,” HTC CEO Peter Chou said, demonstrating a feature that lets you ring your phone when it is lost in the house or send a lost-and-found message to appear on a phone you left in a cab.

By building both HSPA+ and LTE networks, De la Vega said that the company will offer more speed and flexibility.

“More importantly, we will deliver an experience our competitors will not be able to match,” De la Vega said.

As I noted yesterday, there are lots of reasons for Qualcomm to want Atheros, not the least of which is its extensive customer list.

Qualcomm’s specialty has always been in CDMA technology, the flavor of mobile phone technology favored by Verizon Wireless and Sprint, and it collects considerable royalties around its patent portfolio there. It has struggled to penetrate other markets, and last year shuttered its FloTV operation amid minimal demand. The good news was that it sold its FloTV spectrum to AT&T for $1.93 billion, which is no doubt offsetting the cost of this deal. Add that to the $10.3 billion in cash and short-term investments on its balance sheet as of Sept. 26 and this is an easy deal to do.

It’s also the biggest deal in Qualcomm’s history and the first significant one under CEO Paul Jacobs, who is the son of founder Irwin Jacobs.

Atheros shareholders have plenty of reasons to smile today as well. The company’s stock price surged by 19 percent yesterday. At $45 a share, Qualcomm is paying more than Atheros has ever been worth in its entire history as a publicly held company. As Shira Ovide over at Deal Journal notes, its highest price before yesterday was $43.90. Happy New Year, indeed.

I caught up with Qualcomm Executive Vice President Steve Mollenkopf and Atheros CEO Craig Barratt to talk about the deal.

NewEnterprise: Steve, let’s start with you. What got Qualcomm interested in Atheros?

Mollenkopf: Historically Qualcomm has been focused on the cellular phone, though recently we’ve done much more than that. We had some integration relationships with some companies that allow us to deliver a platform to our customers. They’re essentially technical relationships, and one of those companies was Atheros. So we were familiar with them. But the real reason, the why Atheros and why now question comes down to this. We think the industry is moving to a place where a lot of the technology and use cases that are being created as part of the shift to smartphones will be used outside of just phones, and will move into many adjacent spaces. The requirement of technology and different customers overlap a lot with Atheros. They’re a leader in their space, we’re a leader in ours and we want to go into markets that will require the expertise from both of us. It seemed natural, actually.

Craig, the idea for the acquisition seems to have grown out of an existing partnership. When did the talk turn from being Qualcomm’s partner to becoming part of Qualcomm?

Barratt: The partnership has gone on for about five years, where we’ve cooperated on joint reference and designs and software and feature integration. Over the years we’ve broadened out from Wi-Fi, Bluetooth, GPS, powerline and optical networking. We do have a much more horizontal business. Qualcomm has a very strong vertical business. Through our partnership we saw the teams had a good cultural fit, the engineering teams really respect each other. When we looked at our own strategic imperatives over the long term, we saw that cellular technologies are going to be applied in a much broader markets over time, beyond just smartphones and tablets. There’s an intersection between the Qualcomm technology and our technology, and that’s only going to increase. You’ve probably heard that set-top boxes and things like that are going to start to run Android. So a lot of these mobile technologies are going to start showing up in things like the connected home. Strategically it all started to make sense.

And what will your new job be at Qualcomm?

Barratt: After the acquisition closes, which should be in the first half of 2011, my role will be president of Qualcomm Networking and Connectivity, reporting to Steve.

Steve, if I’m not mistaken, this is the biggest deal that Qualcomm has ever done.

Mollenkopf: You’re correct. For us on the Qualcomm side this is a big step toward expanding our business beyond our traditional platform business and we’re doing it in a way that is in line with how the industry is changing. A lot of the things we’ve been doing with Atheros are things we’ve already been doing as part of our relationship, so this is a natural next step.

The idea, he said, is pretty simple: Identify places where there is a lot of cellular congestion and build Wi-Fi networks there.

Over the next several months, Towerstream plans to expand an existing pilot Wi-Fi zone in New York and also hopes in the next year to add wireless “hot zones” in San Francisco and Chicago.

While its core business is selling Internet service to businesses, Towerstream hopes to wholesale its hot zone networks to cellular carriers looking to improve their performance in congested areas.

“We don’t see that problem going away anytime soon,” Thompson said. “It’s really a real-estate issue, not a technology issue.”

The idea of using Wi-Fi to ease cellular overcrowding doesn’t seem that crazy these days. Just last week AT&T announced its own hot zone plan for San Francisco and New York.

The idea of hot zones is not new for Towerstream either, Thompson said. The company first had the idea about four years ago, but at the time there were few Wi-Fi capable phones and not the kind of mobile data congestion seen in big cities.

For now, though, Towerstream’s announcement is mostly a statement of intent, rather than a detailed plan. The company still has to acquire many of the rooftop rights it needs to build its hot zones, and it hasn’t said where within each city it will offer the wireless connections.

Towerstream also doesn’t have any announced carrier partnerships, but Thompson said that it is in trials and said the Wi-Fi hot zones it is building will be capable of working with multiple carriers simultaneously.

“We know there is a lot of value in these networks,” he said.

In fact, the Bay Area unit was one of the first parts of Nokia that CEO Stephen Elop visited when he took the job earlier this year–in part because the company’s board had already scheduled to have its meeting in the area.

Silicon Valley has slowly become an important spot for the company, despite the fact that Nokia doesn’t sell all that many smartphones in the U.S.

Earlier this month, the company’s area employees got a new home as Nokia consolidated nearly all of its Bay Area workers in new offices in Sunnyvale (see picture above). Each floor of the Finnish-style interior has self-standing structures that from the outside look like saunas, but are actually “privacy huts” used for small group meetings or just some alone time pondering the ins and outs of the cellphone business. Nokia kept its research labs in Palo Alto and Berkeley so they could stay close to the area’s top two universities.

The local staff is doing a range of different things. About 50 of Nokia’s Silicon Valley employees come from the company’s 2008 purchase of a Norweigian company called Trolltech, which makes an application platform called QT that is used to control everything from phones to trains and more.

There are also a variety of individuals and small groups working on various product and research efforts. Kari Pulli is a Nokia Fellow who focuses on camera technology. He helped develop a panorama photo feature that is part of the latest Nokia cellphones. His team also developed an HDR photography capability–a feature Pulli reminds people was added to Nokia’s phones before Apple included it in the iPhone. He said his team is currently working on techniques to improve cellphone pictures taken in low-light conditions.

Typically, such photos are either noisy or blurry, depending on what step is taken to compensate for the lack of light. But by taking two pictures–one picture that aims to be sharp, though noisy, and another that will be a bit blurry, but have low noise–he said that a better composite image can be created.

Pulli, who was born in Finland but has spent the past four years in Palo Alto, said he is not too worried that the new Nokia chief is not Finnish. “At least he’s Canadian,” Pulli said, pointing out it’s another cold, dark place that loves hockey. (Elop does love hockey.)

While some of Nokia’s workforce is building new features, others are working on making sure that the company has partnerships with all the important companies in the valley–especially the Facebooks and Twitters of the world.

As for the research projects, they vary widely, and many are only tangentially related to Nokia’s core phone-making business.

Tico Ballagas is a user experience researcher working on how to make technology a better tool for family communications. So he’s been spending a lot of time with Elmo as part of a Family Story Play project to see if distant relatives can better connect with young relatives by reading a story to them over videoconferencing gear.

Meanwhile, Jorg Brakensiek is working with a number of German carmakers to develop a framework known as Terminal Mode, which would allow all manner of smartphones to be usable within cars without users having to stare down at a screen to make use features like maps, email and more.

What many at the offices lament, though, is the fact that so few of the people in the U.S. get a chance to appreciate their work. While Nokia certainly has its challenges globally, it is all but invisible at the cutting edge of the U.S. market. that’s because none of the major carriers here sell a subsidized model of the company’s high-end phones.

What’s worse, the phones that the carriers do sell tend to be the most basic and boring of cellular designs. The company has plans to change that next year, when it hopes the introduction of Meego-based phones will finally sway U.S. carriers to offer subsidized Nokia smartphones, ideally by next summer.

Over the years, printers have progressively shifted from PC accessories to devices that can work independent of PCs. They started small, as dedicated 4×6 printers that had built-in memory-card readers and used basic photo-editing capabilities, and have matured into models like last year’s HP Photosmart Premium All-in-One with Touch-Smart Web that offered apps for printable things like maps, coloring book pages and recipes.

The $400 HP e-All-in-One (http://3.ly/DP8b) takes this concept a step further by enabling even more independence from the PC because its tablet—named the Zeen—is more robust and can browse the Web, check email in a dedicated email program and run a limited selection of apps. It also works as a stand-alone tablet when detached from the e-All-in-One, though it only connects to the Internet via Wi-Fi rather than a cellular connection. It runs on the Android 2.1 operating system, but can only access certain apps rather than any app in the Android Market.

Perhaps an even more important new feature is that this all-in-one will print anything emailed to it from any device connected to the Internet, thanks to ePrint, a cloud-based printing system. This system assigns an email address to the e-All-in-One during its set-up and almost anything sent to that email address will print out, including attachments, no matter where the email is coming from.

One catch is that you must only send the document to the e-All-in-One’s email address and can’t CC anyone else or add another address to the “to” line of the email. A spokesman for HP said that this is done to prevent spam print-outs because batches sent to several people won’t print.

HP also has an exclusive relationship with products running Apple’s latest iOS 4.2 operating system for hand-held devices. Apple’s iPads, iPhones, and iPod touches now have a built-in feature called AirPrint which allows them to print anything directly to HP’s new ePrint printers as long as these devices and the printer are connected to the same Wi-Fi network. I tested this several times using an iPhone and it worked, printing Web pages, emails and photos. I liked the ease of using ePrint and AirPrint. Printouts looked sharp and printed quickly.

But I found the concept behind the e-All-in-One’s detachable tablet screen to be both alluring and confusing. It’s great to be able to do more with the printer’s touch screen and apps—but you don’t want to stand at a desk looking down at this screen, so it makes sense that the tablet is detachable. On the other hand, tablets often work in place of printed paper. I use my iPad for things like finding a recipe online, standing the iPad on my kitchen counter and cooking from that on-screen recipe. If I used the eStation All-in-One like that, I would ultimately print less often, which seems to defeat the purpose of having this big thing in your home. The HP eStation All-in-One measures about 18 inches wide and about 14 inches deep.

HP’s Zeen tablet can be detached from the e-station, but its uses as a stand-alone are questionable.

In order to save energy, the eStation All-in-One goes to sleep when it hasn’t been used for 15 minutes. This is a fine idea for environmental reasons, but in sleep mode, it also turns off its connection to the local Wi-Fi network. This means that if documents are emailed to its assigned address it may not print if it’s not awake and online. An HP spokesman said the company recently issued a fix for this problem that wakes up the printer when something is sent to it, but not all printers have been updated.

The Zeen tablet’s battery recharges every time it’s docked in the eStation All-in-One’s base, and HP estimates that its battery life is around four to six hours with Wi-Fi turned on. Hard buttons for volume and power are hidden on the Zeen’s back edge, as are speakers. A spokesman for HP said that eStation All-in-Ones will be updated early next year to run Android 2.2, which is faster and plays Flash videos.

The Zeen’s four gigabytes of internal memory hold roughly 100 apps, 35 of which come pre-loaded on the tablet. These include apps for MapQuest, Disney, Facebook and the Barnes and Noble bookstore, from which digital books, magazines and newspapers can be purchased and downloaded. Photos, videos, music and other files must be stored on an SD card in the Zeen’s SD card slot.

All documents sent to the e-All-in-One using HP’s ePrint can be seen online at hp.com/go/ePrintCenter as long as users register their printer and set up an account, which I did in about two minutes. Here, too, users can add or remove apps from their printer. I preferred adding and removing apps directly from my Zeen tablet’s screen, but it takes some digging to find the Add More icon for adding apps. Over a dozen HP products support ePrint; they range from $100 to $450.

The concept of ePrint is a smart one, but the printer’s tendency to go into sleep mode to save energy is a problem. I like that the Zeen tablet detaches from the e-All-in-One, but its functionality as a tablet with limited apps and capabilities isn’t very sensible.

Mossberg http://ptech.allthingsd.com/?p=1610 After seven months of unchallenged prominence, Apple’s hot-selling iPad now has its first credible competitor in the nascent market for multitouch consumer tablet computers: the Samsung Galaxy Tab.

The Tab is being introduced over the next week by three major U.S. wireless phone carriers at $400 with a cellular data contract, or at $600 with cellular capability but no contract. The iPad starts at $499 for a Wi-Fi model with no cellular-data capability or contract, and is $629 for the least expensive model with cellular data capability but no contract.

Like the iPad, the Tab, which uses Google’s Android operating system, is a good-looking slate with a vivid color screen that can handle many of the tasks typically performed on a laptop. These include email, social networking, Web browsing, photo viewing, and music and video playback. It also can run a wide variety of third-party apps. But it has major differences, most notably in size.

The Samsung Galaxy Tab has less than half the screen real estate than that of the iPad.

The Tab has a 7-inch screen versus the 9.7-inch display on the iPad. That may seem like a small difference, but the numbers are deceptive, because screen sizes are always described using diagonal measurements. In fact, the actual screen real estate on the Tab is less than half of the iPad’s. That’s a disadvantage, but it allows the overall unit to be much smaller and lighter, and thus more easily used in one hand, something some users will welcome.

The new tablet will be introduced in coming days by Sprint, T-Mobile and Verizon, with a variety of cellular data plans. AT&T also will carry the Tab during the holiday season but hasn’t announced its timing or data-plan pricing. Although it is being sold by cellular carriers, the Tab, like the iPad (which offers optional month-to-month cellular data through AT&T) can’t make cellular voice calls.

I’ve been testing the Tab for a couple of weeks and I like it. It’s a serious alternative to the iPad and one that will be preferred by some folks. It includes the three most-requested features missing in the iPad: a camera (two in fact); the ability to run Web videos and applications written in Adobe’s Flash software; and multitasking, though, to be fair, the latter feature is coming to the iPad imminently via a software update. Another strong point is that like Apple, Samsung has rewritten some of the standard apps, such as the email and calendar programs, to make them look more like PC programs and less like smartphone apps.

On balance, however, I still prefer the iPad. For one thing, I like getting twice the screen size for a little more money up front—as little as $29 for the no-contract model with cellular capability. For another, the iPad has vastly more apps specifically designed for a tablet versus a smartphone—about 40,000 according to Apple, compared with just a handful for the Tab. And it can run about triple the apps overall, if you count smartphone apps that aren’t optimized for tablets.

Also, in my tests, the iPad’s battery life was about five hours better than the Tab’s, its maximum storage capacity is higher, and its aluminum body is more rugged than the Tab’s plastic casing. Finally, the iPad can be bought in a Wi-Fi-only model that frees you from any entanglement with cellphone carriers. The Tab also has Wi-Fi, but, so far, no Wi-Fi-only version, though Samsung is promising one next year.

Still, the Tab is a very attractive product and I enjoyed using it. For buyers who want to spend less up front, don’t mind the smaller screen, prefer the more compact dimensions and one-handed usability, and place high value on the cameras and on Flash, it may well be a better choice.

Hardware

The Tab is a rectangular slate about two inches shorter and three inches narrower than the iPad. It is also a tad thinner. It weighs less than a pound, compared with 1.5 pounds for the iPad. While its screen is smaller, it has almost the same resolution as the iPad, so almost as much material can be displayed on it.

The screen is sharp and generally responsive to touch, though, in my tests, a bit slower than the iPad’s screen. The Tab comes with 16 gigabytes of flash storage, the same as the base iPad. But with some carriers, this storage is internal and in others, it’s on a removable memory card. The card slot comes on all models and can hold up to 32 gigabytes at extra cost. The iPad, also at extra cost, comes in versions that go up to 64 gigabytes, all internal.

With its lighter weight and smaller size, I found the Tab easy to use while standing and moving. It easily fit in one hand, though for many tasks you’ll still need two hands.

Battery Life

Samsung and its partners make wildly varying battery claims for the Tab. The former says it can last up to 13 hours on a single charge, while T-Mobile claims just eight hours. I gave the Tab the same test I used for my iPad review: I put the screen on nearly full brightness, left the Wi-Fi on to collect email and played back-to-back videos until the unit died. My test Tab lasted six hours, 50 minutes, though at six hours, 10 minutes the screen dimmed irrevocably to a darkness level that made it useless. In the same test last spring, the iPad logged 11 hours, 28 minutes.

Cameras

The Tab has a 3-megapixel rear camera with flash and a 1.3-megapixel front camera mainly for video calls. Still-photographs and videos I took were of average quality, but videos taken with the front camera were fuzzy.

I tested video calling using a pre-release, tablet-optimized version of Qik, the software being preinstalled for this purpose on the Tab. Results were mixed. It will work over either cellular or Wi-Fi connections, but the version I tried wasn’t tuned for cellular, so we used Wi-Fi. In my conversation with a Qik executive, the call at first failed to go through. When it did go through, it worked fine for awhile, and then failed when I tried a feature designed to hide my image. Later, the audio dropped altogether. Qik says it is fixing the problems.

Software

The Tab uses the latest version of Android, and it generally worked very smoothly, even though Google has warned that Android isn’t yet ready for tablets. I was especially impressed with Samsung’s attractive and usable rewrites of the calendar, email and contacts apps, which, like their iPad cousins, use multiple panels to make them more computer-like, while still remaining touch-friendly.

I found the Web browser to be a bit jerky in zooming into text and scrolling through long pages. I tested several Adobe Flash videos and websites written in Flash. Sometimes they played and sometimes they didn’t. In all cases, they slowed the browser down. On one site written in Flash, I got a warning saying I might want to “abort” lest the computer become “unresponsive.” In another case, the Tab crashed. So I conclude that while the Tab does play Flash, it needs work on that score.

I downloaded a few third-party apps. I couldn’t find any that were rewritten with extra features for tablets, nor any way to discover these in the Android Market. Some of my downloaded apps scaled fine to tablet size. Others were surrounded by large black bars.

Cellular pricing

On an iPad, if you opt for cellular-data service, there is no contract and only two monthly prices—$14.99 for 250 megabytes and $25 for 2 gigabytes. On the Tab, it’s much more complicated. Verizon, which is selling only the $600 no-contract model, says its pricing will start at $20 a month for 1 gigabyte of data. Sprint charges $29.99 monthly for 2 gigabytes and $59.99 for 5 gigabytes. T-Mobile has different prices for no-contract and contract models, and different rates for new and existing customers. Just two examples: a new customer under contract on a Tab can pay $30 monthly for 200 megabytes or $50 for 5 gigabytes.

So, I urge Tab buyers to do the math carefully on the overall cost of the device under various carriers and plans.

Bottom Line

The Tab is attractive, versatile and competitively priced, though monthly cell fees can add up. It’s different enough from the iPad, yet good enough, to give consumers a real choice.

Mossberg http://ptech.allthingsd.com/?p=1603 If you’re shopping for a new computer this fall, you won’t find big surprises. But you’ll still have to juggle a lot of technobabble terminology and watch your budget. Perhaps the biggest question for some buyers will be whether to get a tablet or a laptop, now that Apple’s iPad is a proven hit and a flood of competitors is on the way.

So, here is my annual fall computer buyers’ guide, a simplified road map to the key decisions shoppers must make. I’ve focused on laptops—the most common purchase—but much of this advice also applies to desktops. As always, these tips are for average users doing the most common tasks. This advice doesn’t apply to businesses, to hard-core gamers, or to serious media producers.

Tablets vs. Laptops: If you’re looking for a light-duty, highly portable computer, it’s worth considering the iPad, which starts at $499, instead of a small laptop. This is especially true if you’re in the market for a secondary computer, or one mainly for use on the go. Many owners of iPads, including me, are finding it handily replaces a laptop for numerous tasks, such as Web browsing, email, social-networking, photos, video and music. It has superior battery life, lighter weight, and it starts instantly. I don’t recommend it for people who are creating long documents, especially spreadsheets and presentations, even though it is capable of those tasks. And I don’t recommend it for users who require, or prefer, a physical keyboard.

If you don’t like the iPad, there will soon be alternatives. For instance, Samsung’s Galaxy Tab, which has a 7-inch screen versus the iPad’s 10-inch display, and runs Google’s Android operating system, will be available this month from major wireless carriers. Sprint, for example, will offer it at $400 with a two-year contract. But some tablet buyers may want to wait till the first half of next year, when many more models will be available, and Apple will likely roll out the second-generation iPad.

Netbooks: These low-cost, low-powered little Windows computers are losing popularity, but are still available, typically for about $350 to $500. They are being hurt by the rise of tablets and by light but larger laptops. Some buyers also find the screens and keyboards are too cramped. But these are evolving. Some now have bigger screens and roomier keyboards. And Dell will soon introduce a sort of hybrid netbook-tablet. Called the Inspiron Duo, this model, starting at $499, has both a regular keyboard and a touch screen that flips around when the lid is closed to act like a tablet.

Windows vs. Mac: Windows laptops can be much less costly—and come in many more styles and varieties—than Mac laptops. The Macs start at $999, versus as little as $500 for a decently equipped Windows portable. Windows laptops are still dominant. But Apple laptops are stylish and reliable, and usually boot much faster than Windows machines, in my tests. Also, Apple scores high on surveys of customer support. Its latest models, like the new, light MacBook Airs, have extraordinarily good battery life. Macs also aren’t affected by the vast majority of malicious software, have much better built-in multimedia software and, at extra cost, can run Windows programs in cases where Mac equivalents aren’t available.

The light but speedy 13-inch Toshiba R705 offers good battery life.

Cost: Most of the popular consumer Windows laptops cost $500 to $800. You can get full-size laptops for as little as $280, but their processors and graphics are weak and some lack webcams. If you can afford it, a light but speedy 13-inch machine like the Toshiba R705 offers very good battery life for just under $800. All-in-one desktops typically cost around $1,000 and some, like the HP TouchSmart, offer touch screens with special touch software. Apple’s popular all-in-one iMac starts at $1,199.

Processors: The most promoted chips are Intel’s i3, i5, and i7 Core models, the latter two of which can turn on and off some of their functions to boost power or save energy. But there is nothing wrong with buying a PC that uses chips from rival AMD, which usually cost less. For average users, Intel’s older Core 2 Duo still works just fine, even with the latest software. Intel’s weaker Atom processor line powers most netbooks.

Graphics: Integrated graphics, which share the computer’s main memory, are fine for most common tasks, but costlier discrete graphics, which have dedicated memory, can speed things up by taking some of the load off the main processor. They also are better for games. Some computers have both and can switch among them.

Wireless: More and more laptops are coming with optional cellular modem chips in addition to Wi-Fi. These can be handy while traveling, but be warned that they require a cellular data contract, which can be costly.

Connections: If you plan to connect your laptop to a TV, look for a connector called an HDMI port, which is used on most high-definition TVs. Some laptops also come with a feature called Wireless Display, or Wi-Di, which, with an extra-cost adapter, can beam your laptop screen to a TV without a cable. There is a new, much faster USB port, called USB 3.0, but, so far, it’s on very few machines.

Memory: Aim for 4 gigabytes of memory, or RAM, on a new computer, and never settle for less than 2 gigabytes.

Hard disks: A 320 gigabyte hard disk should be the minimum on most PCs, though 250 gigabytes is OK if price is key, or if it’s your secondary machine. Solid-state disks, which lack moving parts and use flash memory like smartphones do, are faster and use less battery power. They cost much more, but are coming down in price fast. However, they typically offer much less capacity.

64-bit: Many models now use a 64-bit architecture, which allows properly written software to use more memory and run faster. If possible, buy 64-bit, which will become more and more important.

Touch: Some Windows 7 computers have touch capability built into the screen, though Windows wasn’t designed with touch as a core element and the combination isn’t ideal. Computer makers try to resolve this with special touch software, which you should try in a store. Apple laptops use huge touch pads as the multitouch surface, instead of the screen.

As always, don’t buy more machine than you need.

What program would you recommend for saving Web articles such as yours and which also provides for filing them by classifications such as technology, taxes, health, investments, etc.

A:

There are a number of programs that will let you quickly and easily save links to Web pages you want to save or read later.

One is called Instapaper. Another, which I have recommended in the past, is Evernote. The latter allows you to categorize Web links or any other notes with tags, or to store them in different notebooks that you could label and organize for different topics. Using these tags and/or notebooks, you can quickly find all saved links to Web pages on different topics.

Q:

I always am wary of installing any Microsoft program on my Mac because of viruses. I have, however, been thinking of getting the new Office 2011 for Mac that you reviewed because I have not been happy with the iWork program from Apple. Should I have these virus concerns?

A:

Microsoft’s Office for Mac is a purely native Mac program and doesn’t involve running the Windows operating system, which is the platform on which nearly all viruses operate. So, when it comes to the danger of viruses, Office for the Mac is like any other Mac program—highly unlikely to expose you to viruses.

The one exception is that, years ago, there was a rash of viruses that spread through the use of macros, or automated features, in certain Office files. These could theoretically still plague you, but Microsoft long ago took steps to snuff out most of these, and you can choose to disable macros in any documents you open.

Q:

Several times a year, a group of my friends rents a house in England or France. None of the houses has Wi-Fi. What is the cheapest and easiest way to access the Internet on our computers?

A:

Assuming the houses also lack wired Internet connections, I’d investigate cellular data connections, either via cellular modems for each individual computer, or devices like the MiFi, which create a Wi-Fi network for multiple computers using the cellular data network. I cannot say whether this would be a “cheap” method, as it would likely vary depending on which carrier you used.

Near the end of his opening keynote address, Lazaridis–after making a number of big announcements, including in-app payments for BlackBerry apps, a BlackBerry Advertising Service and the opening of BBM as a social platform–uncrated the PlayBook, RIM’s long-rumored tablet.

Lazaridis described the device as “the first professional tablet,” able to access the “full Web” (the fashionable euphemism for supporting Adobe’s Flash). The PlayBook will be able to display content from a paired BlackBerry smartphone, and, in a departure for RIM, will be “an amazing gaming platform,” Lazaridis said. Leaving no superlative unturned, he said, “This will enable a new world of computing that you can hold in the palm of your hand.”

Thankfully, he stopped short of calling it “magical and revolutionary.”

The PlayBook has no cellular connection of its own, though it can connect to wireless networks through a paired BlackBerry. There are plans for 3G and 4G versions of the device, though RIM volunteered little in the way of a time line for them–“some point in the future” was as close as Lazaridis got to a hard and fast date.

Interestingly, PlayBook doesn’t use RIM’s new BlackBerry 6 OS. Instead, it’s built on a new platform created by QNX, which RIM (RIMM) acquired earlier this year.

Here are the specs:

• 7″ LCD, 1024 x 600, WSVGA, capacitive touch screen with full multi-touch and gesture support
• BlackBerry Tablet OS with support for symmetric multiprocessing
• 1 GHz dual-core processor
• 1 GB RAM
• Dual HD cameras (3 MP front facing, 5 MP rear facing), supports 1080p HD video recording
• Video playback: 1080p HD Video, H.264, MPEG, DivX, WMV
• Audio playback: MP3, AAC, WMA
• HDMI video output
• Wi-Fi – 802.11 a/b/g/n
• Bluetooth 2.1 + EDR
• Connectors: microHDMI, microUSB, charging contacts
• Open, flexible application platform with support for WebKit/HTML-5, Adobe Flash Player 10.1, Adobe Mobile AIR, Adobe Reader, POSIX, OpenGL, Java
• Measures 5.1″x7.6″x0.4″ (130mm x 193mm x 10mm)
• Weighs less than a pound (approximately 0.9 lb or 400g)

Say what you will about RIM following the puck again, that’s an impressive list. In spec, PlayBook looks quite promising, certainly more so than the other iPad rivals we’ve seen to date. And RIM’s leadership clearly has high hopes for it.

“We are bringing mobility to the Web, not asking the Web to reformat for mobility,” RIM co-CEO Jim Balsillie told Reuters. “I can’t think of anything more architecturally game-changing that we’ve done, other than the launch of the original BlackBerry.”

The PlayBook is expected to arrive at market in the U.S. in early 2011 and abroad in the second quarter. No word yet on pricing (or a few other details, like battery life).
