2010 was a very bad year for me to pick to go Mac. After hearing such good things about the hardware. I bought a MacPro, a MBA 11" for me, and a MBA "13 for my wife, Last year first one of the CPU's had to be replaced in the Pro, then 6 months ago the card in my wife's MBA went out. 2 months ago the other CPU went bad in my Pro (I just got a $600 HP desktop rather than spending another $700 just for the CPU). Today my video craped out. 4 major hardware failures on 3 different machines. I gave it a good shot but think I'm back to machines I can repair and plug and play.
