Clearly due to the current heat on Microsoft concerning the Xbox 360 RROD, disk scratching, and overheating scandals, Sony's Dave Karraker is mooning on the company's official blog over a recent PS3 Vault "stress test" called "How to kill a PS3 console" which showed the company's game system to be surprisingly resilient in the face of extreme conditions. "A lot of noise has been made recently about the reliability issues of one of our competitor's systems," Karraker said, then went on to kick some sand in Redmond's eye by adding "Did it fail? Nope. Like the Energizer Bunny, it kept going and going and going." Admittedly, the tests -- which included running games and Blu-ray movies for 108 hours in a typical "living room" environment, placing the console in a freezer van then lowering the temperature from 50 degrees to zero, and powering the PS3 in a sauna where heat increased from 100 degrees to 120 degrees over a nearly three-day session -- were quite extreme. In the end, however, the testers say besides being "extremely hot" after coming out of the sauna, the system is running fine and back in regular use. Microsoft, the ball's in your court.
