Only had my new 2012 iMac for 3 days now and I'm absolutely loving it. It's my first iMac so I can't compare it to previous iterations, but I am so incredibly impressed by the sound quality that this machine pumps out. I'm also impressed by how thin it is and how it STILL somehow manages to get that amazing sound out. Oh, and that screen... Is GORGEOUS! So what have you lot been most impressed with?
