Personally I desperately want a new Mac Pro, my 2006 2.66 has been nothing but a headache (I miss the old PowerPC days when this crap didn't happen as often). I have had countless part replacements (logic board, power supply, super drive, MULTIPLE graphics cards, you name it....) and Apple promises every time that I will get a replacement computer.
I'm going to be out of warranty by the middle of this year and I still haven't gotten a replacement. I'm pretty disappointed with the service I've had so far on this machine. My lowly Macbook has been more reliable.
Ironically I hope that just one more thing goes wrong with it before June because I have names and numbers this time of people higher up the chain at Applecare and they promised me a replacement the next time something happens.
Anyone know how to kill a mac pro? haha.
