How do you read in bed? Lying on your back or on your side? Or perhaps a littel of each? If you read lying on your side, the iPad could present a little bit of a problem: it will maintain a vertical image when what you really want might be a horizontal image (i.e., head on pillow, looking at the page). Seems pretty minor, but this could be a unpleasant for some folks. Will people just adapt or will the device be improved somehow?
