Here's a little bit of background: I bought a 24" iMac in early 2009. In the last 2+ years that I've owned it, it's been repaired SEVEN times. Most of those have been major repairs (logic board, screen replacement, etc.). Well, today I noticed that my screen is suffering from burn-in problems once again. Finally fed up, I call AppleCare (thank goodness I bought that) and asked them to please replace this machine. After e-mailing them pictures of the problem, they agreed that a replacement was in order. They arranged to have me take it to my local Apple Store to do a swap. So... I get to the Apple Store tonight and after getting all the information straight (apparently the person who agreed to do the swap was gone, so they had to examine the case files briefly), they agreed to swap the machine for a 27" i5 model. I asked if it would be possible to upgrade to an i7 model and pay the difference. They said no problem. The Genius then goes in the back and returns a few minutes later with the new computer. Then he tells me, "you're in luck, we're going to swap your machine with the i7 model at no cost to you." Wow. I was just about to hand them over $500 and then didn't have to. Anyway, just wanted to share. The new machine is awesome so far, of course. Hopefully I won't have the problems I had with the old one!
