Atrix 4G: Faux Laptop With a Phone For Brains

Walter S. Mossberg — Wed, 16 Feb 2011 22:37:55 +0000

Today’s best smartphones are really hand-held computers. They run a vast variety of applications, from productivity programs to games, that mimic what laptops do. Their biggest limitations for serious work, gaming, Web surfing and multimedia are their small screens, cramped keyboards and tinny speakers.

[ See post to watch video ]

So, what if you could use the brains and connectivity of such a hand-held computer to drive a laptop-size screen, keyboard and speakers, thus overcoming these limitations? Well, Motorola Mobility has devised a new phone and accessory that aim to do just that: to make the phone the only computer you need.

I’ve been testing this new phone, the Atrix 4G, an Android device that will cost $200 with a two-year contract and will run on AT&T’s network. It’s slated to be available by March 6. I’ve also been testing its unusual and clever accessory called the laptop dock, which looks like a large netbook, with an 11.6-inch screen, full keyboard, touch pad, and stereo speakers. This dock, the price of which depends on when you buy it, has no processor, no file storage and no connectivity of its own. It’s dormant until you plug the Atrix into a slot behind the screen.

When you dock the phone, the faux laptop comes alive. It duplicates the phone’s screen on its larger display and lets you use its connectivity and apps. It also contains a battery that charges the phone. The image of the phone’s screen, and any of its apps you run, can be actual size or blown up to use the dock’s larger screen.

With Motorola’s Atrix 4G smartphone, the laptop is the accessory. The phone shown docked to the laptop dock.

Full-Screen Firefox

Even more interestingly, the dock gives you access to a full, and full-screen, PC version of the Firefox Web browser. Firefox is tucked away inside the Atrix but is available only when the phone is plugged into the laptop dock or a second, smaller dock that’s meant to connect to a TV or desktop monitor. The smaller dock lacks a built-in keyboard, battery or screen.

The laptop dock costs $500, but AT&T will knock the price down to $300, after rebates, if you buy it at the same time you buy the phone. That brings the combined price of both devices to $500—the same as the separate price for the dock. The smaller dock, called the multimedia dock, costs $190.

In my tests, the Atrix and the laptop dock performed mostly as advertised. The phone had no trouble driving the larger screen or the full Firefox browser.

I was even able to insert a flash drive into one of the dock’s two USB ports and copy songs, photos, videos and documents into the phone’s internal memory using the keyboard and touch pad. I edited and wrote text in an app called Quickoffice on the phone using the laptop dock’s keyboard, and ran various other apps, including the popular game Angry Birds, on the larger screen.

The Firefox browser worked as normal, using either the phone’s cellular or Wi-Fi connections to access the Internet. And both the phone itself and Firefox can run Flash videos, which mostly played fine.

But the combination of the phone and dock wasn’t as fast, smooth or versatile as having a real laptop, even though to use them you’re essentially carrying around a light laptop (the dock weighs 2.4 pounds). Many apps on the phone aren’t as polished or powerful as typical PC apps, and I found them clumsier to use with the keyboard and touch pad, as opposed to the touch screen for which they were designed.

Installation Issue

Also, other than Firefox, you can’t install PC programs. You can use Web apps inside Firefox, such as Google Docs or the stripped-down Web versions of Microsoft’s Office apps. For email, you can either use the program based in the phone or any Web-based program via the Firefox browser, such as Gmail or Yahoo Mail. But you can’t, say, install iTunes, or PC-based games, or the full versions of Outlook or Microsoft Word.

And there is only a primitive file system, limited to the capacity of the phone, which is just 16 gigabytes, with an option to expand to 48 gigabytes.

The dock’s screen required a lot of scrolling when using Firefox, partly because the browser has a lot of menus and toolbars. To address this, Motorola lets you convert Web pages to versions with the Firefox controls stripped out, so you just see the content.

There’s another problem with the laptop dock. When you make or receive a voice call while the phone is docked, you must rely on the phone’s microphone and speakers, hidden behind the screen of the dock. As a result, calls sounded muffled on both ends, even though the phone automatically switches into speakerphone mode. Motorola says it is working on this issue.

Despite the drawbacks, some folks will surely be attracted to this innovative combination.

If you mostly do your computing tasks on a phone or a PC Web browser, storing files in the cloud and using phone or Web-based apps, Motorola has you covered. And the fact that the dock can charge the phone is a big plus.

Motorola’s Atrix 4G

The Phone Side

What about the phone itself?

Well, it’s one of the nicest smartphones I’ve tested. Its processor makes it fast, and it has a 4-inch, high-resolution screen—almost as high as the iPhone 4′s, though not quite as sharp to my eye. It runs an older version of Android, but Motorola is promising an upgrade.

The phone also has good battery life. It lasted a full day while I was testing it and Motorola claims up to nine hours of talk time. Photos and videos I took with the phone were sharp, and it has a front camera for video calls.

The Atrix also has two other notable features. First, it can take advantage of AT&T’s souped-up 3G network, which the carrier calls 4G because it can supposedly achieve 4G data speeds.

In my tests, in the D.C. and New York areas, the speed wasn’t especially impressive, averaging just a bit better than 3G speeds on other AT&T phones I’d tested.

There is also a fingerprint sensor built into the phone, which you can use instead of a pass code to secure the phone. It worked fine for me.

Overall, this is a very nice Android phone that can imitate a limited version of a laptop. That may be enough for some folks, but fall short for others.

It's Hard to Cut the Charging Cords

Katherine Boehret — Wed, 16 Feb 2011 00:24:07 +0000

What if there was a product that made it easy to charge all your household mobile devices and it used just a single cord to do it?

Charging pads are designed to do just that. The WildCharge Pad from PureEnergy Solutions Inc., one of the first charging pads, seemed revolutionary when it came out three years ago. It’s a small, thin pad covered in panels that conduct electricity. It plugs into the wall, and devices can be casually dropped onto it so they can start juicing up.

[ See post to watch video ]

Yet, here we are still fumbling around to find the right charging cord to plug into our phones, iPads, digital cameras and portable music players. This week, I decided to investigate why charging pads haven’t caught on with consumers.

One reason is that people may not want to buy a charging accessory when gadgets come with their own cords. Also, for devices to work with these charging surfaces, they must have special backs or cases that correspond with the pad. These can change the look of a device, making them bulky.

However, manufacturers of smart phones and other gadgets are starting to incorporate the technology behind charging pads at the design level so they aren’t so obtuse. Palm Inc., now a subsidiary of Hewlett-Packard, designed a $20 (after instant rebate) accessory called the Touchstone that works as a magnetic charging dock for its Pre smart phones. A special backing still must be swapped out for the Pre’s regular back, but this looks just like the phone’s regular backing. And last week, when H-P unveiled its TouchPad tablet, due out this summer, the company confirmed this device would also work with a Touchstone charger.

Energizer’s Inductive Charger

But why isn’t there one charging pad that works with several different gadgets and doesn’t require an unattractive sleeve? Of the different charging technologies, there isn’t one that has gained a toehold.

A group called the Wireless Power Consortium—which includes a host of different companies like smart-phone makers, wireless carriers and TV makers—created what it intends to be an international standard for interoperable wireless charging, called Qi (pronounced “chee”). The WPC hopes manufacturers will eventually make devices that are Qi compliant so they all work with the same charging pad and don’t require a sleeve, since the technology would be built in. Products using this charging standard would have a Qi logo on their packaging. Compared with the current situation of using different chargers for each device, Qi sounds heavenly.

Though the WPC includes members like Samsung, LG Electronics, Verizon Wireless and Motorola, none of the companies has introduced a Qi-compliant product. When I asked a Motorola spokeswoman if it had plans to use the Qi standard in its products, she would only say that the company is evaluating the technology for future devices. Likewise for BlackBerry-maker Research In Motion Ltd., a WPC member. A spokeswoman said she couldn’t comment on future product plans.

In September, another trade group, the Consumer Electronics Association, created a panel to sort through various opinions on wireless power technical standards. The sole aim of the group is to collect and share information with manufacturers. This group is examining five issues that include: nomenclature; safety; radio-frequency emissions and efficiency; and standby measurement. A CEA spokeswoman said the panel and the WPC share many of the same members and that the panel plans to share information on a charging standard.

Duracell’s myGrid charging pad, which uses the conductive charging technology.

There are two types of charging technology and it isn’t clear yet which one will become the standard. The Qi standard involves a technology called inductive charging, while other companies, like PureEnergy Solutions, use a conductive charging technology.

One big difference is that inductive chargers don’t require metal-on-metal connections to charge a device like conductive chargers do. This means inductive charging will work through lots of different materials, including wood, plastic or leather. This could allow pads to be built into different surfaces, such as airplane trays and office furniture. Late last year, the first Qi-enabled wireless charging station was installed at Windsor International Airport in Ontario.

One product that is Qi compliant is Energizer’s $89 Inductive Charger (http://energizer.com/inductive), but this still requires sleeves for devices. The sleeves cost $35 each and are available for BlackBerrys, the iPhone 3G or 3GS and iPhone 4. Late this summer, Energizer will introduce a universal adapter with micro- and mini-USB compatibility.

Powermat USA’s $60 Wireless Charging System for the iPhone 4 (powermat.com) uses a slightly different technology that requires devices to rest on charging pads in specific positions.

On the conductive front, PureEnergy Solutions has licensed its WildCharge Technology to other companies. All licensees feature a WildCharge Mark of Interoperability on their products so consumers know which products are compatible with the WildCharge charging pad.

Duracell uses this technology in its MyGrid line of products (http://3.ly/A7Yh), including the $85 iPhone Starter Kit and a $90 cellphone starter kit. RadioShack will use WildCharge Technology in its $50 Enercell Charging Pad (http://3.ly/6gcY), which will be available in June, and skins for devices that charge on these pads will cost about $30 each.

In the future, hopefully, one of these committees will figure out which technology is best to establish one standard that saves people from using a rat’s nest of power cords.

THQ Exceeds Guidance After Selling 1.2 Million uDraw GameTablets

Tricia Duryee — Wed, 02 Feb 2011 23:37:54 +0000

THQ reported third-quarter earnings today, exceeding internal guidance because of strong sales of its own uDraw GameTablet, a $70 art accessory for the Nintendo Wii. It shipped 1.2 million units in the quarter. Still, the videogame developer and publisher reported a loss of $14.9 million, or 22 cents a share, compared with a year-ago profit. THQ’s revenues totaled $314.6 million, falling 11 percent from 2009. In after-hours trading, THQ’s stock dropped nearly 13 percent to $5.60 a share.

Exploring iStuff at CES With Mobilized (Video)

Ina Fried — Tue, 11 Jan 2011 01:14:59 +0000

With a little time left at the end of the Consumer Electronics Show, I finally had a break from private meetings, press conferences and onstage interviews. I used the time on Saturday morning to briefly tour a section of the massive show floor.

Given that I only had about an hour for my grand tour, I decided, in true Vegas style, to explore the first thing that came to me when I entered the show floor. Fortunately, since I cover mobile stuff, that turned out to be the iLounge-sponsored Apple area. It took me back to my early days of covering MacWorld Expo, back when it was an event Apple attended.

Some of the vendors were names I recognized, like Speck and Griffin and Mophie–companies that I had covered since their early days, companies that I had watched transformed from start-ups to serious players amid the explosion in the market for companion products to the iPod and, later, the iPhone.

There were also plenty of companies that I had never heard of, eager to find global distribution for ideas ranging from an iPod speaker resembling a gramophone to stickers that make the back of an iPad appear to be etched with a portrait of Barack Obama, Steve Jobs or Bill Gates, among other famous faces.

There were also T-shirts, headphones, keyboard attachments and even a booth with a representative of the Electronic Frontier Foundation.

My only purchase of the day came after I had left the show entirely, though. With some urging from BoomTown’s Kara Swisher, I splurged on Pinball Magic, an accessory that transforms an iPod Touch or iPhone into a pinball machine, which was on clearance for $25 at the Brookstone store in the Las Vegas airport.

Here’s a video look at some of what I found.

Kno Prices Its Student Tablets at $599 and $899 to Ship by End of the Year

Kara Swisher — Tue, 09 Nov 2010 05:00:01 +0000

Kno, the high-profile Silicon Valley start-up trying to jump-start a market for tablets focused on students, announced tonight that it will have a limited number available by the end of the year for sale at prices of $599 and $899.

The lower price is for its single-screen device, while the clamshell double-screen version is more expensive.

Kno would not say exactly how many it has ordered for its first tablet production run–the device is being built by China’s Foxconn–but co-founder and CEO Osman Rashid said in an interview earlier today with BoomTown that units would number “in the thousands.”

Rashid said the Kno tablet will initially be aimed at 10 college campuses across the U.S., although he also declined to name them.

“We are going to do online and offline marketing, in a very focused approach,” he said, noting that Kno would be working with some college bookstores too.

Marketing a new and complex product like the Kno will take a lot of effort and cash, especially since it is an increasingly competitive market for mobile and portable computing products that includes Apple, Microsoft, Hewlett-Packard, Google, Amazon, Dell and many others.

Kno recently raised another $46 million in funding to add to a $10 million round, and sources said that the Santa Clara, Calif., company could be back out raising even more early next year.

Its current backers include prominent venture players like Andreessen Horowitz and First Round Capital, along with investors Mike Maples and Ron Conway.

Kno’s Rashid said his company pushed the go button after getting good feedback from students in a beta test, half of whom used the single-screen device and the other half the two screens, along with its related education platform software.

“We found that 85 percent of those using the single screen wanted the dual-screen version and that those using two screens took three times more notes,” said Rashid. “Students said they love the fact that they can write in the textbook itself and it appears the way it needs to be, even in digital form.”

The first Kno will have an aluminum body, and the company will also offer a set of accessories, such as a cover and a stand.

And Kno will watch initial sales carefully. “As a start-up, we want to make sure we are meeting demand, but also that we roll it out in a careful approach,” said Rashid.

Indeed–and it will be interesting to see how that goes for the ambitious and innovative Kno.

Until the results are in, here is the official press release from Kno:

Kno Announces Pricing and Pre-Order Availability for Tablet Textbook; Pays for Itself in 3 Semesters

Delivers Significant Student Impact for Less than 1% the Cost of a 4-Year College Education

Santa Clara, CA–November 9, 2010–Kno, Inc., a powerful, groundbreaking tablet textbook designed specifically for students and the education market, today revealed the price of its 14.1 inch single and dual-screen tablets at $599 and $899, respectively. The company also announced that it is now accepting a limited number of pre-orders for an initial shipment that is expected to be on customers’ doorsteps by the end of the year.

“Kno’s extraordinary benefits represent only a tiny fraction of the overall cost of college, but its impact on the student’s career–and the energy it adds to the experience, the thrill of learning, and the ultimate grade–is dramatic,” said Osman Rashid, Co-Founder and CEO of Kno, Inc. “Even better, when you do the math, it actually pays for itself and still saves $1,300 in digital textbook costs.”

Kno has been beta-testing the product with students and the response has been overwhelmingly positive for both the single and dual screen devices. Far more than just a digital textbook, Kno is creating a powerfully effective new learning environment that will make students at all levels more successful at processing, grasping and retaining both facts and concepts.

“My experience with Kno has been really incredible. My books have become more interactive and the ability to hand-write electronic notes on the book pages themselves has changed how I retain information,” said Melissa Lin, a sophomore majoring in Biology at UC Berkeley that has been beta-testing the Kno tablet. “I see a ton of difference with the Kno. I can carry everything with me including my books, my notebooks and a browser for research. And, with the lower cost of digital textbooks, it will pay for itself in three semesters which is really great.”

Digital textbooks, which typically cost between 30 and 50 percent less than physical textbooks, will be priced separately and will be sold through the Kno bookstore, which will be accessible on every Kno device. Starting today, students will be able to browse Kno’s bookstore at www.kno.com/store/books, which will include tens of thousands of the most popular textbooks and supplement materials. Kno has previously announced that it is working with major textbook publishers including Cengage, McGraw Hill and Pearson. The company recently added publishers including Macmillan, Bedford, Freeman & Worth and Holtzbrinck as well as BarCharts Publishing, Kaplan, Random House and a large number of the University Presses.

“According to the not-for-profit College Board’s 2010 report, the average college student spends approximately $1,100 a year on book and supplies,” said Babur Habib, CTO and Co-Founder of Kno, Inc. “Kno can reduce that cost while bringing education into the 21st Century, providing students with a far superior learning experience than they have today.”

Smartphone Price Cuts Ruining Long-Term Price Potential?

John Paczkowski — Mon, 23 Nov 2009 15:32:50 +0000

As we head into the holidays, smartphone prices are dropping to points that belie their advanced feature sets. While this is great news for consumers, it may well be problematic for smartphone manufacturers.

According to NPD Group’s latest Mobile Phone Track study, price cuts on devices like Apple’s (AAPL) iPhone and RIM’s (RIMM) Blackberry Curve inspired a three percent decline in the average price for all cellphones in the third quarter of 2009. The overall average purchase price for mobile phones in the U.S. for the period: $85. A year ago it was $88.

An interesting trend given the fast-advancing feature sets and presumably high development costs of the new state-of-the-art smartphones we’re carrying around these days. For while these lower prices mean more sales for smartphone manufacturers and more subscribers for their carrier partners in the short term, they may well be undermining the smartphone’s price potential in the long term. It’s hard not to see the $299.99 Palm (PALM) Pixi for $24.99 on Amazon (AMZN) or the $499.99 Droid Eris for $49.99 on Overstock (OSTK) as having some deflationary impact once those retailers are done with them.

“That impact will continue,” NPD analyst Ross Rubin told me. “The iPhone 3G at $99 has created a benchmark that competitors are responding to with handsets such as the Droid Eris and Palm. Even where a handset is competing closer to the $200 mark, carriers and retailers are using buy-one-get-one promotions (that help lock in family plans). And retailers are discounting even value-priced smartphones further to drive store traffic and accessory sales.”

Rubin’s conclusion: “We will soon reach the point where the handset is a minor expense consideration and the required monthly data fees become the limiting factor in smartphone adoption.”

Second Chances: T-Mobile Tries Again

Katherine Boehret — Wed, 22 Jul 2009 00:08:02 +0000

As the saying goes, you never get a second chance to make a first impression. But it never hurts to try. This week, I tested the T-Mobile myTouch 3G with Google (GOOG), which is the company’s second chance at introducing a “Google phone” to the masses.

Google’s first device, called the T-Mobile G1, came out in October and was less than a sensation. The phone had a touch screen and a handy slide-out physical keyboard, but it was bulky and unattractive. It came with just one gigabyte of memory and lacked important features like compatibility with Microsoft Exchange for use with work email. Its app store, called the Android Market, offered only about 50 applications. The G1 launched with surprisingly few accessories.

[ See post to watch video ]

The $200 (with two-year contract) T-Mobile myTouch 3G (t-mobilemytouch.com) available Aug. 5, has fixed many of these problems. Its new design uses an on-screen keyboard, which gives it a thinner, more stylish build that feels great in the hand. It now comes with four gigabytes of memory, works with Microsoft Exchange and can record and play back video footage. The Android Market has increased its number of apps to about 6,300, and the myTouch will hit stores with accessories like designer shells and docking stations. Its combined voice and data plans are at least $25 less per month than what AT&T’s (T) plans cost for users of Apple’s competing iPhone.

But while using it, I couldn’t help thinking that the myTouch felt less like a new device and more like what the G1 should have been in the first place.

The myTouch, which is built by HTC of Taiwan, runs on an improved version of Google’s operating system, that performs tasks faster has a more streamlined look and supports stereo Bluetooth connections. But it carries on many traits of its predecessor. It still synchronizes over the air with Google account information including email, calendar and contacts. Swiping a finger to the left or right on the myTouch’s home screen will still open other screens, with space for icons representing apps. And its handy window-shade-like Notifications menu can still be pulled down onto the screen at any time to show a list of new messages.

The most dramatic difference on the myTouch is its on-screen keyboard, which may frustrate some people who liked the G1 for its because it had a physical keyboard and a touch screen. Like on Apple’s (AAPL) iPhone, the myTouch keyboard corrects words as you type, recognizing you’ll make more mistakes on it than you would on a physical keyboard. The keyboard suggests words in a horizontal bar that appears above the keyboard and below the text area. You need only type “Washi” and the word “Washington” appears in this bar for you to select. These shortcuts speed up the otherwise frustrating process of on-screen typing.

Unlike on the iPhone, the myTouch keyboard’s keys don’t get larger as your finger hovers over them so as to help you touch the right key. Nor does a word become magnified when you’re trying to place the cursor at a certain spot. The myTouch’s trackball can be used to pinpoint a specific letter but I usually forgot all about the trackball, opting to use the responsive touch screen for navigation.

T-Mobile offers much less expensive monthly plans for the myTouch than AT&T offers for the iPhone. The cheapest voice and data plan from T-Mobile costs $55 compared with AT&T’s $70. Unlimited data and messaging plus minimum voice plans total $65 for T-Mobile and $90 for AT&T. And AT&T’s messaging is currently limited to text, while T-Mobile messaging includes text, picture and video.

On the other hand, T-Mobile offers 3G coverage in far fewer cities than AT&T. The myTouch comes with only a fourth of the built-in memory of the same-priced the 3GS iPhone, and half the memory of the 3G iPhone model, which is costs half the price. And myTouch offers only about a tenth of the apps the iPhone offers, and has a smaller screen.

T-Mobile wants myTouch users to understand apps and download them, starting with the AppPack: a package of eight to 10 apps that T-Mobile will send to myTouch customers via an SMS with a link. Customers can peruse this list of apps and download just the ones they choose. While some people may not appreciate receiving apps suggestions, it could also introduce apps to people who didn’t know how they worked.

The Android Market, where all apps for Google’s phones can be found and purchased,still isn’t as well organized as it should be. It separates games from other applications and organizes them by popularity and date, but doesn’t separate those that are free and those that must be bought. I downloaded several free apps including WordGame, Facebook, Twitter, Sketch-a-Etch and Sherpa. But I was especially irked by the way some of the apps I downloaded kept trying to get me to download additional apps every time I opened them. The Twitter app, which was listed as one of the most popular, displayed prompts to download browsers and RSS readers—even six days after I first used the app. An on-screen message gave me the option to “Ignore Forever,” but this apparently didn’t include prompts to download other programs. Any user would be confused and irritated by these unsolicited messages. Google said that was what the developer chose to do—a major downside to the Android’s open model.

The myTouch’s 3.2-megapixel camera and video camera worked well and started up quickly. An icon labeled Gallery neatly holds still images and videos. And the myTouch has simple ways to upload photos to Picasa or videos to YouTube.

A built-in tool for Google Web searches using voice commands worked remarkably well, even when I tried to trip it up by saying four words at once. It didn’t recognize my last name, but I’ll let it off the hook since it’s spelled differently than it sounds.

The T-Mobile myTouch 3G costs $50 more than the G1, but its extra features are worthwhile. Be ready for a frustrating first-time experience with the on-screen keyboard and try to read user comments in the Android Market to figure out which apps prompt you to download additional programs.

The myTouch is what we expected from Google the first time around. Time will tell if people are ready to give it a second chance.

Two New Devices Give Presentations Some Portability

Nick Wingfield — Thu, 11 Dec 2008 02:08:05 +0000

Digital projectors are the best way to get the biggest possible image for a PowerPoint presentation or a movie. But the projectors are often pretty big themselves, with even most “pocket projectors” too big to stuff into the typical pocket or laptop bag.

That is changing. A new miniature-chip technology from Texas Instruments (TXN) called pico is making digital projectors truly portable, instead of merely luggable. For the past couple of weeks, I’ve been using two of the first pico-based projectors on the market, Dell‘s M109S and Optoma’s Pico PK-101.

The products are designed for different customers with different needs. Dell (DELL) positions the 13-ounce M109S as a notebook companion, best suited for work presentations. The four-ounce Optoma projector is designed more as an iPod or digital-camera accessory for watching movies and slide shows on the go.

The Dell M109S

Their portability requires compromises, most obviously in brightness and image resolution. The Dell and Optoma projectors, respectively, support 11 and 50 lumens — a standard measure of projector brightness. That’s far dimmer than top-notch projectors that offer several thousand lumens. So neither product excels in well-lighted rooms, where overhead and ambient lighting overpower their images. You can compensate somewhat for this weakness by placing the devices closer to the surfaces onto which they’re projecting — for example, a wall. But the darker the room you use, the better.

At about the size of a candy bar, the $399 Optoma device is the smaller of the two projectors and the one with the most intriguing possibilities for expanding the tiny screen sizes of mobile devices like the iPod.

It’s powered by a rechargeable battery that Optoma says lasts for an hour on full brightness or two hours on a power-saving setting (the projector comes with two batteries). The projector has a tiny speaker, but people who want decent sound will need to use headphones or external speakers.

In theory, the Optoma device is small enough to bring along on a camping trip to show a film on the side of a tent, or to a restaurant, where you could inflict a vacation slide show on dinner mates by projecting onto a napkin or tablecloth.

I tested it on a recent airplane flight by projecting an episode of “Mad Men” from an iPod touch onto the back of the seat in front of me. The seat was a dark blue with embossing on it, so it didn’t work very well. It’s best to project onto an unmarked, light-colored surface. The quality of the image was better when I lay in bed one night, projecting a video onto a white ceiling.

Even under the most favorable circumstances, however, I found the images from the Optoma projector very dark, muddling the outlines of characters and action on screen. Although Optoma says you can get up to a 60-inch image from the projector, 45 inches was about as big as I could make the image before it got too fuzzy.

Optoma says the projector will ship with an iPod-compatible connector cable when it goes on sale in the U.S. on Dec. 15, though the unit I tested didn’t come with one. I connected the device to my iPod touch using a $50 cable from Apple (AAPL).

Compared with the Optoma device, the $449 Dell M109S is a behemoth, yet it’s still only about the size of a short stack of drink coasters. Most projectors weigh at least a few pounds, if not more, which is big enough to make them a hassle to carry around. I barely noticed the Dell projector inside my laptop bag.

Unlike the Optoma projector, the Dell M109S has to be plugged into an electrical outlet to work. It comes with an unsightly set of connectors for plugging the projector into a video source, such as the VGA port found on most laptops and a composite video plug that is standard on DVD players. I was, however, able to plug my iPod touch into the Dell projector using the $50 Apple cable.

And unlike the Optoma, the Dell doesn’t have speakers. To get sound for a movie, you’ll need headphones or speakers, like those on a laptop.

Despite its extra bulk, the Dell M109S literally outshines the Optoma projector. It produces a bright image that I found very watchable, even if it wasn’t high-definition. I projected the movie “James and the Giant Peach” onto an interior wall of my house, creating an image that was about 7 feet, measured diagonally.

The Dell M109S includes a capability called keystone correction, a standard feature in most projectors that adjusts a projected image to give it the proper dimensions, rather than the trapezoidal shape that results when a projector is angled upward. The Optoma projector doesn’t have this feature. To get a normal rectangular movie image, I had to hold the projector level, toward the projection surface.

For business travelers who do presentations or for people who want to create a theater-like experience in a hotel room, vacation house or against a sheet in the backyard, the Dell projector would be a good fit. For now, the Optoma projector is a good idea that needs refinement.
