Oh. Well that makes sense. It is so weird for me to think that Macs have different versions too - older and newer. But it makes sense. Did you have to learn PC for work? Which one did you know first, and was learning the other one really difficult? When I say they are impossible, I mean I could not get the mac to do even the most simple thing. It is like a completely different universe, using a mac when you are used to PC's.
