Conclusion: The Toshiba Libretto W100 is a unique ultra-portable PC. It's hard not to love it for its geek factor and uber-daring design; and it targets you well-heeled gadget freaks rather than everyday users. A few years from now, we suspect Toshiba and other manufacturers will offer versions for the average consumer, and the anniversary edition Libretto is testing the waters.
Pros: Unique dual screen design, highly portable, capable CPU., Head-turning design, dual capacitive touch screens, fast CPU for a computer this size, great video playback, full Windows 7 on board. Good virtual keyboards and touch pad. Toshiba's software improves the user experience.
Cons: 7" displays are too small for Windows 7 and touch interaction. Fan blasts., Noisy, non-stop fan. Expensive. Windows wasn't meant for a 7" touch screen (hard to use UI elements, must increase DPI size in display settings). Though the virtual keyboard is excellent, at 7" diagonal, it's cramped for touch typing. Screen glare can be annoying, especially on the lower display.
Summary: For nearly 15 years, Toshiba has been using the Libretto line to test out new concepts and devices. The Libretto W105 is the latest such experiment, and viewed in that regard, it's an intriguing addition. In both design and price, this $1,099 device is meant for early adopters and gadget junkies who will put up with its quirks. It has a number of clever user-interface innovations that make the device easier to use than other Windows 7 tablets.
