For me, the perfect size for a tablet is probably 8.9", but with the same narrow bezel as the G Pad 8.3. My Nook HD+ looks like a monster next to the G Pad, but it's mostly due to the enormous bezel rather than the screen. Until such a device appears, though, the G Pad is a great option!
Felt it in store it is light brilliant screen and superb battery life.
If there was a way to hack it to run stock android I would sell my GPad for it. It is a bit larger but still less than a pound and much brighter higher res screen with close to double the battery life.
