I've never had a Mac, and also, never had a chance to really work with one until I got the job I have now. It convinced me to buy one. I mainly got it for photo/video stuff, but also to finally have one of my own that I could muck around with. Eventually I'll be getting a more powerful one, but this one is doing just fine for now. OS X is what really convinced me to buy one, without it I would've waited a lot longer, or not have bought one at all.
