In that case X360 has a 0% failure rate. As among my circle of friends (about 10 of whom own a X360) there has been 0 failures. But I'd hardly use that to then claim that X360 has no failures.

Similar to me. Out of about a dozen I know with a 360, one has had RROD. I only know 3 people with PS3's, but two of those had issues and needed to be sent back (under warranty) for repair.
But I'm in the same boat in that I would never be so bold to claim either MS has an 8% failure rate, nor that Sony has a 66% one
