Like the Wii, Kinect has accuracy issues. Sometimes you'll think you've hit a ball, but nope! You missed. Winning at table tennis seems to require you to just move your hand back and forth rapidly. There's also the issue of play space -- you need a lot of it, definitely more than you need with either the Wii or the Move. It'll be okay in most living rooms -- except in tiny apartments -- but you might have to move a couch or two.

Kinect's game library is obviously lacking, since it launched in November, but that will quickly change. One Microsoft exec also told PC World there were games in the works for hardcore as well as casual gamers, so both groups could potentially be catered for in Kinect. For now, though, the Wii's library is far superior.

However, there are so many advantages to Kinect that all my complaints about it seem petty. Because your body is essentially the 360's controller, you actually have to use your whole body. That means when you're running in Kinect Sports, you're not just moving a controller up and down to simulate running -- you're actually running. When you play Kinect it gets the heart racing, and it's fun. Really fun.

Conclusion

Rather than repeat everything I've said about the devices, here's a little anecdote: I recently had a group of friends over to try out the Wii, Move, and Kinect. One of them owns a Wii and loves it so much he has all the accessories -- steering wheel for Mario Kart, plastic gun for Overkill. But everyone there, my Wii-fan friend included, agreed that Kinect was the best of the three devices.
