Google Goes To the Cloud For New Idea In PC System

Walter S. Mossberg — Thu, 16 Dec 2010 02:03:25 +0000

In the personal-computer industry, where things change fast, one fact has been a constant for years: There are two major, mainstream operating systems for consumers. One, Microsoft Windows, runs on many brands of hardware and dominates sales. The other, Apple’s Mac OS X, runs only on its maker’s Macintosh computers, and has had a resurgence in popularity in recent years. Other contenders, such as various versions of Linux, have remained on the fringes.

[ See post to watch video ]

Next summer, however, Google hopes to add a third broad-based computer-operating system to challenge the duopoly. It’s called Chrome OS, and is based on Google’s Chrome Web browser. With Chrome, Google isn’t just aiming to elbow its way into the OS business. It’s hoping to change the entire paradigm. Instead of storing most programs and files on your computer itself, the Chrome OS will mainly run programs from, and require you to keep your data in, the cloud—remote servers located on the Internet. In effect, it turns your entire computer into a giant Web browser, instead of treating the browser as just one among many local programs.

The Chrome OS isn’t finished, and isn’t ready for broad public testing. Google readily concedes it has lots of bugs and rough edges. But the company has designed a small test laptop with the new operating system installed and distributed “a few thousand” of them to outsiders to try.

A Cr-48 test machine, with Chrome OS installed. Chrome will be licensed to select manufacturers.

I have been using this machine, called the Cr-48, for about a week, and have some explanations and first impressions to share. This isn’t a formal review; that will have to wait till the product is finished and is on commercial computers.

I focused mainly on the software, which is built on a Linux underpinning. That’s because Google doesn’t ever intend to sell the Cr-48 hardware, an all-black, unbranded laptop with a 12-inch screen, a rubbery surface and a large, buttonless touchpad that resembles those pioneered on the Mac.

In my tests, I found this early Chrome OS machine to be fast, with decent battery life and almost instant resumption from sleep. It handled most Web sites fine, and worked almost exactly like the very nice Chrome browser on Windows and Mac.

I also liked the one hardware feature worth mentioning: a radically redesigned keyboard. Instead of function keys, or various legacy keys such as Caps Lock, Chrome OS keyboards feature dedicated browser-oriented keys, like ones for moving back and forth among Web pages and windows, refreshing a page, entering full-screen mode, or quickly opening a new tab and beginning a search.

The Chrome OS will have a big advantage. Because it is mainly a front-end-to-cloud service, if you lose your laptop, you can get another one and just sign into your cloud accounts. You should be able to find all your stuff waiting for you.

However, users of the Chrome OS will have a huge adjustment to make. They will have to give up the rich, local programs they have spent years learning to use and tweaking to their liking. You can’t install local programs on a Chrome OS computer. Instead, Google provides a Web Store inside the browser that allows you to download icons for “Web apps”—mostly websites designed to look and work like standard programs.

Some of these, like Gmail, are familiar and popular. Others are newer. For instance, the New York Times and AOL already designed Web-based news apps for Chrome OS, and there is a Web-based version of the TweetDeck program for Twitter. These apps, and the store’s own icon, appear on the new Tab screen of Chrome OS (and also are available in the current Chrome browser.)

In my tests, I found these apps generally worked fine. But most aren’t as rich and versatile as local Windows and Mac programs. For example, there was no way to play my local, personalized iTunes music collection, unless I spent many hours uploading it to some Web-based service.

I also had to settle for Web-based productivity programs—like word processors and spreadsheets—with many fewer features than standard local ones, such as Microsoft Office.

And I ran into plenty of frustrations. At this stage, Chrome OS can’t do anything with USB flash drives or SD memory cards, and can’t synchronize phones. And it has a very limited ability to store, or allow you to do anything with, email attachments or other files you might download and prefer to keep locally rather than on a server controlled by somebody else.

Printing was a chore, requiring a complicated setup on a Windows computer that Chrome used as a conduit to a printer.

Plus, Chrome OS is hardly stable yet. I suffered numerous crashes of Adobe’s Flash player, and even Google’s own Google Talk instant-messaging service, which appears in a little pop-up window on top of the browser. The company says it hopes to fix these problems by next summer.

Finally, the biggest downside: Because it’s a cloud-oriented system, Chrome OS is almost useless if you lack an Internet connection. Google says it plans to offer some limited offline functionality, and to encourage makers of Web apps to do the same. It will also eventually be able to make some use of some files stored on external hard disks. But the basic operating mode will require you to be connected to the Internet.

To help with this, the Cr-48 has a Verizon cellular modem built in, to supplement its Wi-Fi connectivity. Verizon is offering 100 megabytes of data free, but that is a small amount, and you have to pay for more.

Like the Mac OS, but unlike Windows or Google’s own smartphone operating system, Android, the Chrome OS will be deeply integrated with hardware. So, Google doesn’t plan to distribute or license the new operating system to every hardware maker—at least not at first. You won’t be able to install it on an existing computer. It will be available in 2011 on a limited number of computer models from selected manufacturers.

Google says this is because security is a high priority and requires special hardware designs that tightly bond with the software.

Also, Chrome OS computers will, in some respects, be more like iPads than laptops. They won’t have hard disks, just a limited amount of flash-memory storage, and they won’t have DVD drives.

They are an attempt to realize the old idea of a “network computer,” or one which is mostly a front end for network services.

Of course, many people already spend most of their time with their PCs and Macs connected to the Net. Many use Web-based email programs or streaming music programs instead of local software.

So the time may be right for a cloud computer, a change in the paradigm. Google certainly hopes so.

The Answers to Your Questions About the iPad

Walter S. Mossberg — Thu, 08 Apr 2010 01:05:14 +0000

Since my review of the new Apple iPad tablet last week, I have been bombarded with questions. This is natural. The iPad is a real computer that overlaps many functions of a laptop, but works very differently from one.

So here are answers to some of the most common questions I’ve received, in hopes they may help clear up any confusion. One caveat: Apple is offering a “sneak preview” on Thursday of a forthcoming revision to the iPhone operating system, which powers the iPad, so some changes might be revealed.

[ See post to watch video ]

Can you print from an iPad? Apple (AAPL) didn’t build in a printing function, so you can’t just tap a menu button to print an email, photo or Web page. But a few third-party apps allow printing of some items from an iPad to a networked printer. One is Print Online. It costs $5 and I tested it successfully. But these apps are complicated and limited workarounds—inadequate substitutes for built-in printing.

The iPad lacks a USB port, so how do you get files into it? Like the iPhone and iPod Touch, the iPad has the familiar Apple connector port and comes with a cable that links this port to a USB port on a PC or Mac. Then, using iTunes on the PC or Mac, you can sync over to the device your songs, photos, videos, contacts, apps and more.

New to the latest version of iTunes is a function that will also transfer to the iPad files like Microsoft Office documents. But this feature only works if you’ve installed on your iPad certain programs that can edit these documents, such as Apple’s optional $10 word-processor, spreadsheet and presentation programs. Documents can be moved in the other direction, too.

You also can get some types of documents into the iPad wirelessly, if you receive them as email attachments or as downloads from the Web. For example, if you receive a Word-document attachment, and you have Apple’s Pages word processor installed, you can send it to Pages, where it can be stored and edited. Pages can then send back the edited version.

Is there a way to type on the iPad without laying it flat and using the virtual keyboard? There are several. Apple sells a $39 case that bends to angle the device in a more convenient typing position (and allows for hands-free video watching). The company also sells a $69 accessory physical keyboard that features a dock at the rear to hold the iPad upright. In addition, you can type on the iPad using Apple’s $69 wireless keyboard for the Mac, which can be held on your lap.

Can I run Windows or Mac programs on the iPad? Not unless their makers produce iPad versions of these programs. The iPad doesn’t run the Macintosh or Windows operating systems, so it can’t run programs designed for them. It runs the iPhone operating system, which is only compatible with iPhone and iPad apps, of which there are more than 150,000. There are some iPad and iPhone apps that let you remotely control Windows and Mac computers, so you could indirectly run Windows and Mac programs via the screen of an iPad, but that isn’t like running the programs locally.

I hear the iPad lacks multitasking. What are the downsides of this? First, let me clarify that the iPad (and iPhone) can technically perform multitasking, or running more than one program at once. But Apple has chosen to limit this ability to some of its own built-in apps, and deny it to third-party apps. For instance, the built-in email program will continue to receive messages while you are watching a movie on the built-in video player.

The downsides of denying multitasking to all apps are considerable. For example, you can’t listen to streaming music from the Pandora music app while checking email. And you can’t view fresh Twitter posts while on other apps. You have to close the app you’re in, then re-launch a Twitter app and wait for it to fetch the new posts. And, you can’t, say, check email or surf the Web while waiting for a complex game to load in the background, because the game stops once you change to another app.

Since the iPad’s battery is sealed in, how do I replace it? The battery isn’t designed to be replaceable by the user. Apple will replace your iPad with one containing a fresh battery for $107, including shipping. The process takes up to a week. Most important, you will lose all your personal data unless you back it up regularly to your computer and restore it on the replacement iPad. Details are at: apple.com/support/ipad/service/battery/.

No File! No Icon! Litl Is a Big Idea, but Still Cloudy

Walter S. Mossberg — Thu, 31 Dec 2009 02:31:29 +0000

One of the hottest ideas in the digital world now is the notion of dumping the traditional personal computer, where most programs and data are stored locally, for a stripped-down device that would operate primarily as a gateway to servers on the Internet, where your programs and data are accessed remotely. This approach is often called “cloud computing.”

[ See post to watch video ]

In fact, the original netbooks, the small laptops that have become very popular, were designed around this concept of relying mostly on the Web. They used low-end processors, shunned Windows, and had very little internal storage. But a combination of consumer sentiment and industry maneuvering pushed them back into the fold, so that today, most are simply cheap, small conventional Windows laptops.

Now, a small Boston company, called Litl, is taking another shot at this idea, with a different twist. It is selling online a highly unusual laptop it classifies as a “webbook,” which attempts to meld cloud computing with a TV-like viewing experience—for the home. This shiny, colorful computer, named the Litl, is larger and more expensive than a typical netbook. It’s about the size of a small standard laptop, with a 12-inch screen and a weight of 3.4 pounds. It costs $699, or about twice the price of a netbook, at litl.com.

Yet the Litl doesn’t use Windows, or directly run word processors, email, or photo or music programs. It can only perform those tasks via Web sites and services like Gmail or Flckr, Google Docs or Pandora Radio. About the only local program it has that can run without an Internet connection is a virtual egg timer. It has no hard disk or any other way for a user to store anything locally.

The Litl’s user interface is a radical departure. There is no task bar or dock, no folders, no icons for files and programs; no traditional desktop. Instead, the Litl’s screen is filled with small cards that contain various kinds of Web content, from photos to news headlines, Facebook status and favorite Web sites. Click on a card, and its contents fill the screen.

The Litl webbook

And the Litl has another big difference from standard laptops or netbooks: something called “easel mode.” You can flip it around so the machine takes the form of an inverted letter “V,” with the screen facing outward. In that position, the machine can be used like a small Internet-based TV to display headlines, the weather, photo slideshows or videos from the Web. The company sells a $19 remote for controlling the computer in easel mode. You can also control it with a wheel built into the hinge.

I’ve been testing the Litl and I have mixed feelings about it. Some of the bold concepts behind the machine are refreshing, including the cloud-computing idea and the very simple interface and operating system, which demand much less work and attention from the user than a traditional PC does. The company also is promising many improvements, delivered via frequent over-the-air updates, including iPhone-type apps developed by third parties. It even offers a two-year money-back guarantee.

I was able to set up cards for Gmail and Yahoo Mail, and to send and receive messages. I also set up a card for Google Docs and was able to create and edit documents. I tapped into my Flickr account and could view slideshows of family photos I had previously uploaded. And I was able to watch TV shows via Hulu, both in easel mode and on my big-screen TV, once I connected the Litl to it.

But, in my tests, I found the device a bit clumsy and unsatisfying to use. For instance, as you add cards for your favorite Web sites or headline feeds (called channels), it becomes more difficult to scroll through screen after screen to find the one you want. There is no easy way to organize things.

In easel mode, when you see a headline that interests you, there is no way to click on it to read the whole story. Videos in easel mode too often stuttered. Worse, if you’re watching a video in easel mode, or through a TV, the Litl’s remote doesn’t let you pause, fast forward or back up. And the Litl doesn’t allow you to upload photos or videos to the Web.

The battery life is awful. The company claims 2.5 hours. In my tests, it conked out in less time. The company says that isn’t a problem, because the machine is designed for home use and will likely stay plugged in.

The company claims it is working on improving the Litl’s shortcomings. For instance, it plans a photo-uploading function and smoother video playback. So, it will likely get better. But, as of now, for $699, my feeling is that a standard laptop could perform many of these tasks in a more familiar, more versatile manner.

Cloud computing may one day be the standard way of doing things digitally, but the Litl, at least in its current form, isn’t the answer.

Droid Memory, Palm to iPod Touch, and iMacs for Older Users

Walter S. Mossberg — Wed, 11 Nov 2009 22:22:58 +0000

I have read that the Motorola Droid from Verizon has a limited amount of memory for storing third-party apps, no matter how much total memory you add to it. Is this true?

A: That’s right. It’s a characteristic of Android, the Droid’s operating system made by Google, and it’s something I noted as a weakness when I reviewed the first Android phone over a year ago.

Even though the Droid comes with 16 gigabytes of memory, in the form of a removable card, apps can’t be stored on this memory card. They must be stored in a special area of internal memory, which in the case of the Droid totals only a measly 256 megabytes, about a fourth of one gigabyte. The memory card is reserved instead for things like documents, music, videos and pictures. That limits the total number of apps the phone can hold at any one time.

Google says the amount of internal memory allotted for apps is up to the hardware makers, and notes that the Droid has twice as much as the original Android phone. It also says that makers of complex apps that use things like graphics that are ancillary to the core app itself could theoretically offload these files to the memory cards.

But users of Apple’s competing iPhone can devote nearly all of its 16 gigabytes of memory to storing third-party apps, allowing many more apps to be stored on the phone.

I have all my data (addresses, calendar, notes) stored on my Palm Zire. I’d like to get an iPod Touch, but can’t figure out how to transfer the Palm calendar. Can you help? Or, do you know of any other “smart” handheld that will allow me to import my Palm data and give me Internet/email access?

A: There are various workarounds for doing the transfer to an iPod Touch, but, since you ask, there is another smart phone with great Internet capabilities that comes with a way to do it simply and directly: the Palm Pre. It’s based on a new and different operating system than your Zire is, called webOS, and is designed to sync with wireless contact and calendar sources rather than desktop programs.

But Palm has developed a one-time, one-way utility for transferring data from desktop software used by an older Palm to one of the wireless calendar and contact services with which the Pre was designed to sync. More information is at: http://bit.ly/2ivFI.

I want to buy a new computer and I really like the new iMac with the 27″ screen. I am 72 years old, which is one of the reasons I want the larger screen. Please tell me if you think my buying this iMac is a good idea. Is there some negative aspect of the iMac that I should be aware of?

A: I gave the new iMac with the huge screen a positive review, so I obviously think it’s a good computer. But, if by mentioning your age you mean to imply that you have vision issues, you should be aware that the new iMac’s screen isn’t just physically large, but is high resolution.

That allows it to pack a lot more content onto the screen, but, depending on what program you’re using, it can make the text small. Word processors, email programs and Web browsers usually allow you to enlarge text, but not all programs do.

The Mac itself has a system-wide zooming feature, but that makes some tasks harder to work with. I recommend you go to a store and play with the big iMac for a while to make sure you feel comfortable with its screen resolution.

Quickoffice Brings Editing to iPhones, But Put It on Hold

Walter S. Mossberg — Thu, 07 May 2009 01:04:03 +0000

I am typing these words in a full-fledged word processor on an Apple iPhone. It’s a third-party app that allows you to edit, format or create Microsoft Word and Excel documents, and then send them back to a PC or Mac where they can be opened in Word or Excel. Oh, and it has cut, copy and paste in its word processor — a capability long missing from the iPhone that isn’t due from Apple (AAPL) itself until this summer.

[ See post to watch video ]

Devotees of older smart phones, tired of iPhone hype, will be quick to note this is no innovation. Devices like Windows Mobile phones, Palm (PALM) Treos and BlackBerrys have made these abilities available for years. But, for the 37 million iPhone and iPod Touch owners, it’s potentially a major step forward, closing a hole in a hand-held computing platform that is otherwise more elegant and versatile than any other.

This new app, called Quickoffice, has some nice features. Its cut, copy and paste function is very well designed. It can save files locally on the phone. It has a built-in email function for sending files to others, and it can upload or download files to and from a PC or Mac, or to and from online storage.

But there’s a catch. While Quickoffice, which is also available on other platforms, did work OK in my tests, it has some major drawbacks that keep me from recommending it right now. The product’s maker, Quickoffice Inc., acknowledges these and is working to fix them by summer. But, especially because Quickoffice costs $19.99, a Rolls-Royce price in the iPhone’s app store, you might want to hold off on buying it until the fixes are in place.

In particular, Quickoffice can’t simply load and edit any Word or Excel file you receive as an email attachment. The company claims this is a built-in iPhone limitation, but it’s still a big problem for users. Instead, to get files into Quickoffice for editing, you have to transfer them using a Wi-Fi network from your PC or Mac, or from the iDisk online storage feature of Apple’s MobileMe Web service, which costs $99 a year.

Also, amazingly, Quickoffice shipped without any automatic typo-correcting function or spell checker. For various technical reasons, it couldn’t even use the one built into the iPhone. So, you have to do a lot of correcting of typos once the file gets onto a computer. For instance, the first words of this column, as originally created in Quickoffice, read: “I am typing these words in a full-feledged word pricessor … ” I had to clean them up in Word on my laptop.

The Quickword app on iPhone

And, while you can view a text or spreadsheet file in landscape mode, you can do only limited editing of text documents in this mode, and no editing at all of spreadsheet documents viewed in landscape.

Quickoffice for the iPhone consists of three modules. One is Quickword, the word processor. The second is Quicksheet, the spreadsheet program. These two, also separately available from the app store at $12.99 each, can handle standard Microsoft (MSFT) .doc and . xls files, but not Microsoft’s newer .docx and .xlsx formats. The third module, called Quickoffice Files, merely transfers and displays files, but doesn’t allow editing or creating them. It handles a much wider variety of file types, and is sold separately for $1.99.

Cut, copy and paste is implemented nicely. You simply double-tap to select a word or triple-tap to select a paragraph. Small dots appear at either end of the selection, allowing you to expand or contract the selected section of text. Once your selection is done, you can then cut it or copy it, or change its formatting. To cut or copy your selection, you just choose cut or copy from a popup menu. To paste, you tap once elsewhere in the document, and then select Paste from a popup menu. You can paste text copied or cut from one Quickword document into another, but not into any other app on the iPhone. (Apple will add that ability this summer.)

Quickword is the better of the two main modules. It has an impressive suite of features, including the ability to bold or italicize characters, change fonts and colors, create bullet points, and undo or redo changes. All of this formatting was retained correctly when I transferred the files to a computer, and vice versa. Quickword doesn’t have every feature of Word on a computer, but its feature set is strong.

Quicksheet has 125 functions. It also does formatting of cells well, and has undo and redo. Again, it isn’t as powerful as Excel, but its capabilities are decent. Unfortunately, unlike in the word processor, I found some problems in Quicksheet. In one simple spreadsheet I imported, it failed to properly display text that stretched across multiple cells, and failed to do a simple recalculation that worked perfectly in Excel. Also, it lacks cut, copy and paste.

Getting documents into the app is a pain. Unless you have a MobileMe account, on either Windows or Mac, you have to type a geeky numerical address into a Web browser and then choose a file from your computer using the browser page that comes up.

Quickoffice is an OK start, but it needs a lot of work.

One Way to Turn a Mac Into a PC Just Got Better

Walt Mossberg — Thu, 02 Oct 2008 01:46:03 +0000

There are two common methods for running Microsoft Windows and Windows programs on an Apple Macintosh, and one of those methods just got better and easier.

The first approach uses a feature called Boot Camp that comes free on every new Mac. Using Boot Camp, the entire Mac is turned into a Windows PC, with the full capabilities and speed of a standard Windows machine. No trace of the Mac operating system is left running. The downside is that you can’t run Windows and Mac programs side by side.

The second approach uses one of two third-party programs to create a virtual Windows PC inside your Mac. This faux Windows machine runs at normal speeds and can operate simultaneously with the Mac’s own operating system. Programs native to each operating system can run side by side. The downside is that, because Windows doesn’t get complete control of the computer’s hardware, it isn’t quite as fast as in Boot Camp, and a few of its functions, like 3D graphics, don’t work as well.

This latter method is enabled by two excellent, closely matched $80 programs: Parallels, from a Swiss-based company of the same name, and Fusion, from VMWare, a U.S. company. It is Fusion that just got better, because VMWare just issued version 2.0 of the product with lots of new features, some of which let it catch up to the older Parallels and some of which push it ahead.

[ See post to watch video ]

I’ve been testing Fusion 2.0 for a couple of weeks on two different Macs, and using it to run both Windows XP and Windows Vista. My verdict is that while you won’t go wrong with Parallels, Fusion edges it out as the better product.

The new Fusion 2.0 is a free upgrade for owners of version 1.0. It can be obtained at vmware.com/mac and at various retailers.

Like Boot Camp and Parallels, Fusion requires you to obtain and install a fresh, boxed, full version of Windows on your Mac. But once you’ve done that, your Mac becomes two computers in one. If you need to run programs that are available only on Windows, you can do so with ease.

For instance, as I write this column on a MacBook pro laptop, using a Macintosh word processor, I am using Fusion 2.0 to simultaneously run Google’s new Chrome browser, which is so far available for Windows only. I can switch between the two with a couple of keystrokes and copy text from one to the other.

Like Parallels, Fusion allows you to run Windows programs in one of three ways. You can see the entire Windows desktop, with Windows programs running within it, inside its own window on your Mac. Or, using a feature called “Unity,” each Windows program can float free, as if it were just another Mac program, with the Windows desktop invisible. If you minimize a Windows program, it disappears into an icon in the Mac’s Dock, just as Mac programs do.

Finally, you can devote the entire screen to the Windows desktop and hide the Mac operating system entirely.

Parallels can also do these things. Both programs can now also “mirror” your most common Windows and Mac file folders so that, for instance, all of the files in your Mac’s Pictures folder also appear in the My Pictures folder in Windows XP. This is a new addition to Fusion, as is the ability to take multiple “snapshots” of your Windows virtual machine, so if something goes wrong, you can roll back to a previous state when things were stable.

But Fusion has some other features Parallels lacks. For example, it allows you to automatically take those protective snapshots at timed intervals. It also permits you to completely customize keyboard commands so that the same common key combinations work in both Windows and Mac programs. It allows the faux Windows machine to take full advantage of multiple monitors, if you have them.

Fusion also uses a more modern and capable version of the proprietary 3-D graphics system in Windows, called DirectX. That means some Windows-only games and other programs that won’t work in Parallels will work in Fusion. I successfully tested two such programs, both from Microsoft: Worldwide Telescope and Photosynth.

And, in my experience, Fusion is a bit faster than Parallels. Both programs put a strain on your Mac when performing major tasks, like starting up or shutting down Windows. But Fusion seems to affect the Mac less. And, unlike Parallels, it can make Windows quicker by optionally assigning it control of the multiple “cores” in most modern processor chips.

Fusion also offers a one-year free subscription to Windows security software, while Parallels offers only a six-month subscription.

However, Fusion has its limits. Like Parallels, it cannot run the 3-D visual effects in Windows Vista. And, in my tests, it wouldn’t allow Windows running on one of my Macs to use the printer that was configured on the Mac, although that feature did work on my other test Mac.

In my view, Fusion is now the better choice for running Windows on a Mac virtually.

Defragmenting a Hard Disk

Walter S. Mossberg — Thu, 25 Sep 2008 00:46:01 +0000

Here are a few questions I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability.

A friend of mine suggested that I “defragment” my computer every once in a while. He says it will boost performance, but he also said it will move my data around. I tend to be very organized as to where I put documents on my computer. Will defragmenting my computer jumble my files and put them into random places?

No. Defragmenting a hard disk doesn’t change or scramble the organization of files and folders that you have established. Your file organization should look just the same after defragmenting the disk. What defragmenting does is rearrange the location on the disk of the data segments that make up your files. In some cases, a single file like a word-processor document might actually be made up of multiple data segments, invisible to you, that are located in widely separated physical spots on the disk. Defragmenting tries to optimize the location of these segments so that the computer operates more efficiently.

I saw your review of Norton Internet Security 2009, and wonder what is the difference between this product and Norton 360?

Norton 360 has the same features as Norton Internet Security, but adds some additional ones, like online backup and PC “tune-up.” It also costs more. However, the current version of Norton 360 doesn’t include the improvements I wrote about in the NIS product that make it faster and less of a burden on your computer. Those are planned for a future version of Norton 360.

Can I use one of the new 3G iPhones as a wireless modem for my Apple laptop?

No. That function isn’t built into the iPhone and Apple yanked from distribution a third-party program that enabled using the phone as a modem. I suspect the reason is a business one, not a technical one. Cellphone carriers like AT&T typically take the position that connecting a laptop to their networks, whether via a data card or via a cellphone used as a modem, should command a higher monthly data charge than they typically levy for a cellphone alone.
