Hi all. This is my first post to the forum and I am a new Mac user, starting with a 27 iMac I bought in the fall. I am 35 and have never used a mac ever prior to this, always having self-built PCs, which served me well until Vista and surprisingly Windows 7 (another story for another time.) In the last few months, I have grown to really like macs, so I got a used Rev A Air on eBay with 14 months of Applecare remaining. First, I really like the Air, it does what I need and has a super cool form factor. I bring it into work and people just love to see it. Anyway, I have been reading the forums and the overheating issues surrounding the Rev A, and mine would overheat as well, not terribly where it would shut down, but it definitely gets hot. So having applecare, I took it in to see what could be done. I took it to the Apple flagship store in San Francisco and the genius there was extremely nice and helpful. I told them it was getting pretty hot and that the hinges had some play in them and asked them to try to address these issues. Got a call today from them and they are replacing the thermal module, replacing the clamshell and my superdrive which had a frayed cord. So the question is - is this thermal module better than the original? Second, does the replacement of the clamshell and hinges include the actual display itself, or is it just the casing? Anyway, I have been extremely impressed with Applecare and all this work they are doing - no questions asked really. And my name isn't even on the Applecare. And although this isn't related, I used Applecare to replace my 27inch imac for display problems as well. After a firmware update, it produced a pink line vertically on the display - replaced the entire computer no problem. Awesome. Really happy with Applecare!
