I'm not sure I get that first one. The reason, IMO of course, that the iPad rotates to any orientation is just for personal preferences. I only ever hold mine in one of two orientations (button at bottom, button at left) and thus I am never 'disoriented'. Besides that, having at least one hardware button is really quite useful when (inevitably imperfect) apps go screwy. Also, non-standard placement of home button, anyone? In short: I think, considering this is a prototype, you wont actually see very many tablets without hardware home-type-button. It may sound good in theory but I expect it would be really frustrating in real life.
