Microsoft has maintained that the problems occasionally reported by Xbox 360 owners are not very prevalent; just a small percentage of 360s are faulty, they say. That may be so, but for one unlucky console owner it's taken seven faulty consoles for him to get customer service satisfaction. The Mercury News discusses the tale of Rob Cassingham, a self professed 'Xbox fanboy'. He and his wife Mindy run a gaming center, and were responsible (via direct purchases and through word of mouth) for more than a dozen 360 purchases. For his business, he had six machines ... and every one of them failed. Even one of the replacements for the original unit failed, and for every replacement he's had to wait two weeks to get a new system. As he puts it, "Why spend money for rims on a car that spends 90 percent of its time in the shop?" After the Merc's Dean Takahashi referred his case to Peter Moore, he finally received a new machine as a replacement for his most recent faulty model. Cassingham is still deciding whether to keep it or not.
