Well, I'm at a loss for words, that's not what I was expecting at all. I was expecting something along the lines of the image sabre2922 posted, that would have been a good competent controller. I'll have to judge for myself though, it's going to be weird playing games with one hand and having the other attached by a small wire, on the plus side its omni dexterous.
No one who hasn't used this yet should really comment weather its good or bad. All in all I'm kind of skeptical on this one. At first glance developers aren't going to like this though.
