Hi Everyone: I've been lurking here for the past few weeks and today I just bought my first iMac. It's the entry level 27" Core i5, AMD 6770M one. I know, I know, half you guys will be breathing down my neck screaming, "RETURN IT!! and buy a 2012 model!!" but I bought it second hand and only paid $1000 for it and it's only 3 months old. I thought I got a pretty good deal on it, but after getting home my spouse started asking the questions I probably should have asked first, like: Will apple still support it if there's a warranty issue or if I need to use the genius bar (since I am not the original owner)? What is the screen life on one of these giant 27" displays? How long does apple typically support their machines? As in, how long will I still be able to get updates for it? If any of you have any ideas, please let me know. I've been a PC user my whole life, but I loved the iPhone so I thought I'd try an iMac when my computer died last month. I was waiting for the new 2012 models, but this deal seemed too good to pass up. I hope I was right!!
