Hands-on preview Japan continues to live up to its reputation for miniaturisation. This week, Fujitsu unveiled a family of small PCs, sized only slightly larger than a hefty PDA, known as the U Series, where the U is taken from Ultra-mobile PC.

Aimed at the corporate user on the go, the unhandily named FMV-U8240 features a desktop operating system - either Windows XP or, for the adventurous user, Windows Vista - as part of the 580g package which slipped handily into my jacket pocket - for testing purposes only, you understand. At 2.7cm thick, it's as thin as a modest paperback book. The diminutive computer caught the fancy of a German colleague who immediately saw a use for this as an on-the-go digital photo editing platform.

A bright 5.6in display with 1,024 x 600 resolution provided a surprisingly easy-to-read screen - provided that you read Japanese easily, that is - the launch of this gadget is scheduled for June (XP) and July (Vista), in Asian regions only. No date yet on when it will reach Europe or North America.
