For serious input, I'd have it lying flat or slightly inclined. For meetings, I'd have it on a stand on the tabletop. For Augmented Reality, I'd be holding it out in front of me, possibly with both hands.

This post was made with a Windows tablet, BTW, as have all my posts for a week. My tc1100 works best lying flat for serious input. I suspect that will also be true for a non-stylus interface.
