13Cent has a good point. I have noticed my that 2 out of 3 of the people I know with an XBox 360 will have problems with it. I know 3 people who even had to send theirs back for a new one because they got the dreaded 'Red Rings of Death.'
I will say it again, The PS3 does have better Stats, but the Xbox has some pretty damn good games out their for it. Get whatever you think will gowith your playing style the best. The PS3 fits mine, so thats why I got it.
