I really like the tech but am not sure they've found the killer app yet, although I think they are going about it in a decent direction really trying to cater to tinkerers and hackers with the SDK & dev kit.

That said, I do think they need to think a little bit harder from a top-down perspective just where this tech might be most applicable. Certainly gaming could be big. But as a general purpose input device, I'm not so sure.
