It's pretty obvious, isn't it?  The Xbox360 uses a tri-core 3.0 GHz PowerPC processor and a special ATi graphics card... It would be the ultimate PowerPC Mac, and OS X might be able to run on it without any special drivers.  Has anyone tried to install OS X on their 360?  I've searched the 'net numerous times for just such an attempt (and hopefully success), but I only get returns on OS X running on (an emulator on) the original Xbox.  If no one has, I have a friend who owns a 360, and I own copy of the retail Tiger install disc.  Conceivably, the Xbox HD could be backed up, wiped, and have the Mac OS installed via a mac.  With the addition of the Xbox360 controller driver, it would be one slick setup!
