I've always felt the same way. Looks really cool, and probably a lot more appropriate for a movie than what people would really use, but really awkward and impractical for the tasks it's supposed to help accomplish. It's sort of like having to swing a Wiimote to swing a sword in a game. Initial novelty value is great, but after a while, if you could do the same thing by simply pushing a button, why wouldn't you just push a button? No matter how good the motion tracking is, if it's not the most efficient way to accomplish the task, there's no point to it. Aside from how cool it looks and the cinematic qualities that made it appropriate for the movie, everything he used that UI for could have been done much more efficiently with a mouse and keyboard-based UI.
