It is so a cool device. I use the UX280 and Q1 at work. But the UX keyboard is good for short writings, but the keyboard on the Kohjinsha lets write you longer texts, like on a normal notebook.
I think this year will be the year of UMPC 2nd generation.

Very helpful intro, Steve.

The size seems blessing and curse here: small enough to be easily held, yet too small on which to comfortably type. The lack of touchscreen seems to defeat the types of functionality that would be expected with the keyboard in hiding mode…
