It's SO fun, way better (IMO) than the Wii. Selecting with your hand sometimes can be a little like trying to get the Wii controller pointed at the right thing, when you're hitting start or whatnot, but once you start playing the game, it just sees your body and you have fun with it.
The only real con I would say is that with really small kids (like under 3) they can get in the way and that drives the older kids nutty. If other people are walking into the frame, it messes things up.
Other than that, it is so fun and the games are great, they just keep getting better. We've had ours since it came out. I'm not a big video game person, but I like Kinect
