Toshiba Libretto W105-L251 review: Toshiba Libretto W105-L251

There's been plenty of buzz for the high-concept Toshiba Libretto W100 series since it was first announced in June 2010. This dual-touch-screen minilaptop is a limited-release showpiece designed by Toshiba to celebrate the company's 25th anniversary in the mobile computing business, and is best seen as an experiment that pushes the boundaries between laptops, tablets, and portable media players.

The Good

Innovative dual-touch-screen design; better-than-expected performance; multiple onscreen keyboard layouts.

The Bad

Disappointing battery life; some awkward touch interaction.

The Bottom Line

Toshiba's dual-touch-screen Libretto W105 is a fun, quirky experiment, but it's still more of an expensive executive toy than a practical PC.

Despite the far-out thinking behind it, the Libretto worked in practice better than we expected in some areas, including certain kinds of media playback and general Web surfing. That was especially surprising, as the system is running Windows 7 Home Premium over two simultaneous displays, all from a 1.2GHz Intel Pentium U5400 CPU and 2GB of RAM. Our configuration (the only one currently available, according to Toshiba's Web site) is called the W105-L251 and sells for $1,099.

Though it certainly can't compete against full-size laptops in raw performance, the system's capability to run basic Windows tasks was impressive (given our low initial expectations). For a largely experimental showpiece that Toshiba says was not intended for wide-scale consumption, the Libretto at least partially delivers on its promise, and is--more importantly--often fun to use. Still, at the end of the day, given its high price and limited availability, this is really more of an executive toy than anything else, especially as it doesn't fully replace any other gadget in your tech arsenal.

Looking a little like an oversize Nintendo DS, the Libretto has two 7-inch multitouch displays (both at 1,024x600-pixel resolution), with the second taking the place of the traditional keyboard one would expect to find in this kind of clamshell design. By tapping a button on the side of the chassis, a virtual keyboard (similar to what you'd find on an iPhone or iPad) pops up to fill the bottom screen. Tap the same button twice and you get a virtual onscreen touch pad instead.

Our first struggle came with figuring out how to juggle these two virtual input devices, as the bottom screen isn't large enough to display both the keyboard and the touch pad fully at once (and, in our tests, the onscreen keyboard and touch pad couldn't register inputs simultaneously). Eventually, we got into a nice rhythm of single- and double-tapping to switch from keyboard to touch pad on the fly, although it's more than a little counterintuitive.

Unlike Apple's iPad, you can't simply use your finger to flick-scroll through Web pages or documents (although we also found some system windows where you could), and working tiny buttons and tabs was frustrating, even when using the onscreen touch pad instead of a finger. That said, the touch controls on the Libretto are among the most responsive we've encountered on a Windows-based tablet (although that's not really saying much, considering the laggy Windows tablets we've used in the past).

Actually navigating around the Windows interface was mostly lag-free, which is something even many Netbooks can't say. At the same time, a 7-inch touch screen, no matter how many navigational tricks you include, simply isn't optimal for touch, and we spent plenty of time hunting and pecking, trying to center the tiny cursor on buttons and tabs.

Pressing the button on the right side of the bottom display switches between the standard Windows OS desktop and a series of Toshiba's proprietary Bulletin Board screens, which allow you to arrange photos and notes on a touch-friendly surface. It looks snazzy, but we can't say it's particularly useful, especially as it (like almost any proprietary app) has its own learning curve.

One of the most important navigational shortcuts is called the Easy Menu Utility. Behind this generic name is an onscreen overlay that appears when the title bar of a window is tapped. A nine-square grid overlays the display, and gives you large tap-friendly buttons for maximizing and minimizing the active window, toggling the window to the other display, or even stretching the active window to cover both displays. It's handy, but having to hide whatever you're looking at behind an overlay, even for a few seconds, suggests that some form of gesture control system might be more useful.

A must-have tablet feature that's included here is an accelerometer for automatically rotating the display when the system is turned on its side. Potentially useful for e-book reading, the display rotation is painfully slow, and when using Amazon's Kindle software, we could not configure it so that one page of a book fit neatly into each screen at the same time.

Ports and connectivity options are predictably limited, but no more so than we've seen on other UMPC systems. There's a single USB port (handy for plugging in an external mouse in a pinch) and a microSD slot, plus a basic Webcam sits next to the top screen. There's no Ethernet jack, but you do get 802.11n Wi-Fi and Bluetooth.

Despite the promise of a 62GB solid-state hard drive, the Libretto is surprisingly noisy. An internal fan kicks in frequently, sounding as loud as a spinning platter-based hard drive. Despite the hardworking fan, the system gets very hot, especially around the vents on the top half, and throughout much of the heat-conducting metal top lid.

The system's benchmark scores were solid compared with single-core Netbooks, which is obviously a benefit of going with a non-Atom CPU, and the application speed was largely comparable with the new generation of AMD-powered premium Netbooks. Video playback of local 720p video files was flawless, but online streaming video was trickier. On YouTube, 480p videos played smoothly, whereas 720p ones stuttered. On Hulu, 480p video was choppy, but the lower-res options worked well, and still looked decent on the small 7-inch 1,024x600-pixel screen. Gaming, as one might imagine, is largely out of the question, although the handful of Facebook games we tried worked fine and animated smoothly.

The flip side of not using a low-voltage Atom CPU is that battery life was not what one would expect from a tiny device made with portability in mind. In our video playback battery drain test, the Libretto W105 ran for only 2 hours and 27 minutes. As many Netbooks can run 5 or more hours on a single charge (to say nothing of your iPad or iPhone), the battery life is another knock against the Libretto as a useful real-world tool.

Toshiba includes an industry-standard one-year parts-and-labor warranty with the system. Support is accessible through a toll-free phone line (at 800-457-7777), and an online support site. The dedicated Libretto W105 page offers a user guide, detailed spec sheet, and a list of available software and driver downloads.
