This is slightly OT, but I have an Xbox 360 and not a PS3 and in many ways I regret my decision. I was very impressed with the original xbox, and never got much into playstation or ps2, so the 360 seemed a natural choice for me. So many problems though. System overheats and crashes after some hours, I already had to send one 360 back for a replacement (apparently i'm in the majority with that..) it was so crappy, no HDMI support initially,, you have to pay to play online, and it just goes on and on. Oh, did I mention it doesn't have blu-ray?
Needless to say they've lost my support when it comes to my next system choice.
The only advantage Xbox 360 has over the PS3 is better price, it's easier to develop games for and (argueably) has better games than PS3.
