Wow, he broke a Jasper in 3 months? I have a feeling this is user error like CGI mentioned. This is the first I've heard of any Jasper unit failing due to RRoD. Sure there is likely still 3% out there that will fail (normal failure of electronics), but the way this guy goes through consoles, it sure makes the problem look more like his fault....
He probably insists on keeping his 360 in a closed cabinet with his ancient electronics that actually didn't need a lot of ventilation.
