survey of 5,000 readers? Eh, I'd like a higher count before looking at any percentages.
My 360 only has problems when I play Tales of Vesperia, which actually caused me to stop playing. It wasn't too bad though, I knew when the system was going to break down when the machine stopped making it's humming noise, which was an indicator to save that game immediately. I've never had troubles on any other game. I think my system is more game prejudice than broken.
Assume that for every 1 reader, their opinion is 90% similar to at least 200 more people.
