Hello everyone, this is my first post here and I'm coming to you all with a question. I'm going into Computer Science at the University of Toronto in September and I want to get a Mac to work on. My problems start here, I have no idea what I should get, I want a machine that will last for four or more years (it is hard to tell what I might want to do that far down the road but I know I don't want to buy a second laptop during school). That's as far as I've gotten, any suggestions to which model I should get?
