What struck me was the jarring use of both "Australian" and "Traditional" scrolling styles on the same device. The selection widgets moved along with your finger, but the room panning moved counter to your finger. That would drive me batty.
The noise while drawing around the room (and outside) was horrid. Nails on chalkboard type horrid. I'd have thought the visual movement was enough to convey the idea that you were navigating. But testing again I guess.
