Does anyone have experience and input on how long it takes Apple to turn around a screen replacement on a 27" iMac? Mine, less than a year old, is starting to drastically loose brightness on the left side only. My concern is with timeframe for a fix -- I'm a freelancer, and without this thing I'm useless. I was told usually this is a repair process that can be done in-store -- of course, no indication on how long that might take. Either way, I'd feel a bit better if I could potentially plan for how long I'll be out of commission. AppleCare / warranty isn't a concern -- I'm good there.
