So here goes. New iMac 27" i7 3.4GHz 12GB Ram in May 2011. Purchased Applecare. 3 months old and line of pixels in screen dies. Take it in and have screen replaced. Would have cost just over $800 if not for warranty. One week. Upgrade to Lion 10.7.3 and it is corrupt. Back to store, and 2 weeks later finally they solve the problem. Told me it took them wiping the HDD several times before they could get the OS to install properly. Told me it was a software incompatibility issue. Not running any illegal software. Run exactly the same software's on my other iMac and have never to this date had any issues. So it cost me $150 out of my pocket and 2 weeks. 6 months ago iMac develops buzzing noise in back. Need to take it in anyways for the HDD recall. Tell them about buzzing and told they would check it out. 1 week later I get iMac back, plug it in and low and behold still have buzzing noise. So issue not solved. I am tolerant so can deal with noise but sure somewhere down the road something is going to go bad. Cost would have been $300. Well last week screen goes black. Do a hard shut down and try to restart. No luck. Get apple and spinning wheel, then black or white screen. Take it to store again. This time they determine it is the power supply causing buzzing noise and screen issues. One week later get it back. Buzzing finally gone. Would have cost me $150 if not for Applecare. Seems okay when I leave the store but now I am leery. Well not more than 2 hours after turning it on, screen starts to flicker and goes black. Try hard reset to no avail. Call Apple directly and talk to senior tech for almost 2 hours. We try several things. Get screen back momentarily but never long enough to get anything done. PRAM, clearing cache, but no luck. Create new partition and try installing OS from disk, but black screen appears. Now the screen is doing all kinds of neat things. Flickering from black to white. Black and white lines. But neat light show non the less. So tech tells me to take it back to store and she will follow up with me later this week. Well back to store it goes just now and genius tells me it is either the logic board or video card. Another expensive fix if not for Applecare. Anyways, this goes to show why Applecare pays off. But since having this iMac, it has been back for repairs for over 5 weeks in total time. So when do I have a right to ask for a new iMac? I own many Apple products (2 iPad's, 3 iPhone's, G4 iBook, 3 iPod's and iMac 21") and have never had an issue with any of them. Now I understand that not all computers are perfect but WTF. UPDATE: Received new iMac yesterday. Gave me several upgrades I did not expect. Now I did have top of line Mid 2011 27" they replaced. Below are the specs I received. Very pleased with results. Nice to see big corp backing their products.
