It seems people want the left motion of the joystick to go back through history and the right motion to go to forward page turns. How are these mutually exclusive?
As far as reading usage, I never use bookmarks (how do you make one?) and I never use history unless when moving/turning a page I accidentally hit one of the numbered buttons (would be nice if these locked while reading or you had to hold for 2 seconds to be active while reading?). When I'm done reading I just hit the little power slider to turn the Reader off, next time I pick it up I hit the slider to turn it back on. The hibernate is fast enough I've never felt a need to leave it on, even if I will be reading again in 10 minutes.
Just make joystick back = go back through history and joystick forward = next page while reading, problem solved!
