While I'd agree that the Kinect for the 360 is lackluster, this Kinect overall is an amazing NI accessory. Its allowing people to really push the envelope of NI applications and the its practical use.
For example, Kinect being used for <a href="http://www.kinecthacks.com/kinect-may-make-gesture-based-surgery-possible/">Gesture based surgery applications</a> or what about <a href="http://www.kinecthacks.com/kinect-essential-for-autonomous-navigation-of-mini-car/">autonomously driving robots</a>. The point is the Kinect is priced so competitively that its really going to be amazing how it pushes forward Natural Interface products.
Personally I think that its just coming to light and you'll see some amazing things soon from even more of the public.
