Fujitsu's endearing diminutive LifeBook UH900 UMPC has been spotted whipping through the FCC [pdf link], presumably ahead of its launch in the US. The filing tests the compact clamshell's Atheros WiFi b/g/n networking card, together with its Bluetooth chipset, though there's no mention of any integrated 3G card being profiled.
The filing also reveals that Fujitsu has both home and commercial sales in mind for the device. The LifeBook is referred to as both the UH900 and U900, the "H" standing for "Home". Specifications of the UH900/U900 include a 5.6-inch sunlight-readable touchscreen with multitouch support, full QWERTY keyboard, 62GB SSD and an Intel Atom Z530 processor. It measures just 20.4 x 10.65 x 2.4 cm and weighs around 500g, and is expected to launch early in the new year.
