I ordered an iMac last week, got a DOA. Sent it back, Apple sent me this one. It works, however the screen is faded yellow on the sides, slightly. Lots of apps, even when they're the only one open, seem to crash. Airport disconnects randomly and can't find networks for hours. It hasn't been 14 days, so I can return it but I know I'd have to wait a few days for the refund, plus my parents will be upset with the fact that I'm not happy with the replacement, therefore even making their opinions on Apple worse. [they don't like Apple, yet we all have iPhones ]. Should I return it, I'll buy a BlackBook. What do you think?
