You have all got it wrong... The Kinect is the hardware and the 360 is an add-on/accessory for it like a power cord or USB cable for a printer.

I was just waiting, i thought that a hater might make a comment back before i could hit the reply button. I (like most of the people on this site as far as i can tell) have all three of the current systems(and a crap load of the older ones). I also have purchased the Kinect for a couple of reasons. 1. I was hoping to get what i thought the Wii would be at some point 2. I have 4 kids 3. Willing to try anything new to make my gaming more interesting. The Kinect works good enough, but i am hoping more challenging games are coming(key word hope). I haven't yet bought the Move, as i have tied it and it doesn't seem to be much different that the Wiimote.
Oh, by the way....... The Kinect is obviously an accessory!
