I’ve seen a similar unit somewhere in Park Square 1 for some months now but it looks like Fujitsu has done a refresh (LifeBook U820) with an Intel Atom processor in it.
Fujitsu packed the whole thing in just 5.6 inches, the smallest I’ve seen so far. It also swivels around to take on a tablet form, with stylus in tow.

Weighs only 1.32lbs (0.6kg). This rig (with the Garmin Mobile PC) can practically serve as a fully-functional GPS navigation system in your car. Too bad it costs a bit on the expensive side — starting price is $999.
