I just saw your thread about the yellow screen issue, is this a reason to not buy an iMac? I was planning on buying a 21.5, but now that I see that, im worried. Are they good computers? Do they have a lot of problems? I don't know much about Macs, I just know that the times I have played with them, I loved them! I currently have a Sony Vaio which has been a great computer, im just sick of Microsoft.:/
