I bought what had the most games at the time. 360 by far. I dont see any games for the PS3 that are so awesome as to sway the vote and make me decide to buy a PS3. Now I know down the like PS3 will win eventually, if so, then I will buy a PS3.
This whole "i'm a amiga fan and I dont/wont support microsoft" thing I'm not in to.. I buy what works. If my son wants a 360 and at the time its kickin PS3 butt then that sounds good to me.
