I'm impressed by the sharpness, colour and readability of the One when its running Linux - what is it like when running XP?
I've seen XP on other 8.9" screens such as the Advent 4211 and everything is so tiny it would be a pain to use.
I find it easy enough to use with xp. One program I need to run needs 600 pixels of screen height in order to show everything. So I had to auto hide the task bar.
With firefox and adobe you can pinch zoom in and out, making it even easier to use.
