I know 2 brothers who had 360 since they came out and each one has had RROD THREE TIMES. My cousin has it....and since joining MKC/U/E i have seen COUNTLESS RR's from many many members. When we look at RR nowadays it appears the comment most frequently heard is "Yea, well 360 is a good system, I only got RR ONCE".
While the competition does seem to be more durable, w/ the existing fail-rate of PS3's much lower, it also poses a threat, and w/out a warrantee to back it up.
For Sony, 100-150$ will get your beloved running again, which ironically is around the same price as the warrantee you can buy w/ it.
