I just got an iMac a few weeks ago, and I absolutely hate it more than any other computer i've ever owned. I have a late 2011 MacBook Pro and it is my baby and I LOOOOVE it, and I love my 4S. I have previously had 3 other iMacs a 2008,2009, and mid 2010 and have had nothing but problems with them. Screen flickering, dead pixels, dropped wi-fi. This unit has a few dust specs and what looks like smears behind the screen. I am not sending it back to apple for a new one because this is a new one and it sucks. I'm debating whether I should buy a pc desktop to replace this iMac or just keep the stupid thing. I am an Apple fanatic, I just have had nothing but trouble with the iMacs.
