Kinect rocks,But The xbox360 RROD and the problems that this console produces it's not worth buying the kinect for an xbox360.I had 7 of them freezing and bricking before i switched over to the ultimate system which is the good old reliable pc.
Well, I bought the XBox 360 the day it came out (it might have been the day after actually), and I'm on my second XBox 360 right now, which is pretty good going considering it's used a lot.
I bought the PS3 within the first month of it's release, and I'm on my second one now, although it's not used anywhere near as much as the Xbox 360 (or the Wii for that matter, lol)
Mathematically, the XBox 360 is winning, but to be honest, both systems work fine if you look after them.
Although I've used other people's Kinect devices, and enjoyed it very much, I still prefer to use joypads for most games.
Even using a touch-screen PC gets tiresome after a while, so as clever as these devices are, I'd hate to see them replace normal peripherals completely.
I'm sure we'll all be long gone by the time that day comes.
Anyway, that's another discussion completely.
