My iMac has been, for lack of a better term, a piece of chit. In the 2 1/2 years I have owned it every component except for the case has been replaced. Screen, motherboard, hard drive, and power supply. This has been inconvenient but no big deal. Apple care has covered every repair. Well February 12th makes 3 years. I'm nervous as hell to own this thing out of warranty. The invoices for each repair was usually $8-1500 each time. Should I bail now and upgrade or wait it out and roll the dice? Since the guts of the computer are actually only a year old will they stand up? Is it a fluke or are other 2010 iMac guys plagued with expensive problems? Now that the new one is out I guess it's a good time to upgrade.
