Returned the Kinect and bought a Playstation Move instead. There were several deal breakers with the kinect. First, the camera it uses in infra-red, and I have a south-facing house with single-pane windows. Whenever there was a significant temperature difference outside, I would “lose an arm” in the game. Brutal. Also, while i have a pretty big house, the “family” room, while reasonably sized, had an overstuffed sectional in it. The Kinect couldn’t seem to realize that this was not “walkable” so there were certain parts of the screen that I couldn’t reach. This is a big reason the Kinect is getting savaged online by apartment dwellers. Finally, of course, there was the lag.
The Move is much more responsive, but while the Kinect games were innovative (including an anti-gravity room), the game that came with the Move seemed like just a port of a Wii game (albeit it a much fancier and better responsive one). However, the advantage of the Move is that Sony can reverse-integrate it into their existing games, whereas the Kinect can’t (or certainly not easily). I’ll have to play around with the Move a little more (it works best with two controllers, but there was only one in the box and they were sold out of additional controllers), so I’ll keep you in the loop. As an added bonus, the PS3 plays Blurays, and is a much more powerful machine than the XBox.
If you have ideal, lab-like conditions, maybe the Kinect is for you (though I’ll reserve judgement until I’ve fully tested the Move). If you don’t the Move is your only option. Either of these leaves the Wii in the dust.
