After recent reports that the Xbox 360 has a failure rate of 30%, one EB Games associate (their level in the company totem pole not clear) said this:
Failure rates for all other consoles were not high enough for EB to consider revising their policies. Most other console systems have a failure rate of less than one percent, including the PlayStation 3.
Sure, it helps that few people are actually playing their PS3s due to a lackluster game library, but you just don't hear about PS3s breaking—while at a recent Nintendo gaming event a gaming journalist confessed to me that half his magazine's staff had to replace their Xbox 360s. The bottom line: Sony builds solid products and keeps manufacturing in-house. Microsoft farms out each component to the lowest bidder, and the practice is hurting consumers.
