My gf just bought me an 27 inch Imac on Thursday. The person she purchased it from at apple said it was the newest version that came out two days ago. I'm not too familiar with Macs (this is my first Mac computer), but I wanted to compare the old version to the new version and make sure she was fooled since she told the guy she really didn't know much about Macs and it was a gift. I'm assuming there are some changes where I can compare against the box.
