I own a high-end gaming desktop PC, but am looking for a new notebook for University. I have zero experience with Mac OS X and have never owned a Mac. I'm looking for some reasons to convince me that purchasing a MacBook Pro is a good idea. Generally, I'll be using the notebook for schoolwork, but I'd also like it to be able to play Starcraft II competently. I'm looking at the i5 or i7 15'' models. So, why should I switch from PC to Mac, any good reasons?
