I think the consoles are pretty reliable this generation considering how hot and complex the systems are. My friend showed me a stat which showed Nvidia graphics cards had like a 16% failure rate on their own. Thats the recent GTX 280 series I think.
I think maybe the perception of the failure rate is greater as the proportion of people who complain are a fraction of the overall population but make a disproportionate number of responses. You never hear anyone complain their car started on a cold morning unless it usually doesn't for example.
