Someone at work bought an Asus R2Hv:

It was about $1000 a year ago, so similar price to the Fujitsu you mentioned. The spec page says that the R2Hv has a 7" screen, so bigger than the Fujitsu. Anyway, this was about a year ago, but the computer was s-l-o-w. Way slower than even the NIT 770. Vista ran like a dog on it, and the interface was just horrible. Even the EeePC is much faster and more usable than the Asus was. Vista is meant to run on a high-resolution display, end of story. Maybe Fujitsu did a better job, I see that the resolution is higher. All the same, I can't imagine that it would be very readable with a 5" screen.

The Fujitsu mentioned here is also three times heaver than the N800. Given the size and weight, I don't imagine that it would be very pocketable. Interesting device, though.
