I was just about to ask that question, I was like DANG! Someone on the forum already beat me to having all three next gen consoles.
Also, the PS3 gets WAAAAAAAAAAAAY hotter than the 360.
But the 360's louder than the PS3, that's where the PS3 has the 360 beat, but other than that small factor, I like my 360 more than my PS3. I don't know why, I just wanted to point that out...
