I know for a fact PS3 and 360 are not the same. PS3 has maybe a 10/11% failure rate while the 360 is like.. close to 50 or even 54. Everyone I know who has a 360 has had theirs crash. But that doesn't mean the PS3 won't have crashes and for yours I am sorry. I hope you get a good one soon. ^^

And that it keeps working!
