Hi, my 6 week old 27" refurb iMac has 3 smallish blue 'patches' on the screen visible only on a dark background. I have decided to have it looked at or replaced if possible. Being in the UK what is the best way to go? I would prefer to have it picked up from me as i don't drive and lugging this thing to an Apple store would be a hassle. If i call Tech Support is having it picked up a viable option?
