There are mobile PCs and then there are ultra mobile PCs (UMPC). The U810 is definitely the latter.
The U810 is likely the smallest notebook we’ve ever tested with a miniscule 5.6" screen and weighing just under two lbs.
But wait, there is more to this diminutive little device: the Fujitsu U810 is actually a convertible UMPC - meaning that it works like a notebook and a tablet PC.
What can you do with such a small device? In fact, you can do a lot, but such a small size brings with it drawbacks in both power and functionality.
