I have all three.

I had the Wii first which I got dirt cheap working at rent a center. I actually put some money into getting a backwards compatible PS3. I just had an xbox 360 given to me because it was collecting dust. I said it might as well collect dust at my house and he gave it to me. I don't know if i'll ever play it though. I actully enjoy the wii, but I need to do some remodding on it before I can play it again and have been too busy playing PS3 to fix it.
