Fujitsu LifeBook U810 review: Fujitsu LifeBook U810

With Intel's new 800MHz A110 CPU, specifically designed for mobile devices like smart phones and UMPCs, the LifeBook U810 takes a step away from previous UMPCs, which used typical laptop CPUs. The difference can most clearly be seem when the U810 struggles a bit with Windows Vista, particularly during the long start-up time, which took nearly 2 minutes. We were able to surf the Web and work on office documents without any slowdown, but in CNET Labs' benchmark tests, it fell behind the Vulcan FlipStart and Sony VAIO UX390, which both had low-power laptop processors, only besting the OQO model 02 with its sluggish VIA CPU.

The LifeBook U810 ran for 3 hours and 15 minutes on our DVD battery drain test, using an external USB-powered DVD drive and the included four-cell battery. That's impressive for such a tiny system, and on par with the Sony VAIO and FlipStart, but the U810 requires an unsightly battery that sticks out from the back of the system. Bear in mind our DVD battery drain test is especially grueling, so you can expect longer life from casual Web surfing and office use.

Fujitsu includes an industry-standard one-year parts-and-labor warranty with the system. Support is accessible through a 24/7 toll-free phone line, and a Web site with online chat, a knowledge base, and driver downloads. Three years of coverage costs and extra $179, while adding on-site service runs $50 per year.
