The Raon everun will rotate automatically as you rotate the device, and the buttons work once rotated in a rotated mode (ie. not like the Q1 above).

I agree; landscape is the best way to read, and a UMPC rocks for ebook reading (although mobpocket needs to improve their ebook readers browser, it is a bit of a PIA, and I haven't found another reader program that is anywhere as nice). I especially like that the Everun runs about 5-5.5 hours between charges.
