MacBook air in college...

Let me add my vote in favor of the OP's choice of the hi-res, AG screen 15 inch MBP. I think that the AG screen is the way to go and the tradeoff you made by giving up the 13 inch MBP's 4.5 pounds in favor of the 15 inch model's 5.6 pounds in order to get higher resolution and an antiglare screen was worthwhile. Don't listen to the nastiness of the naysayers. Those guys look for ways to try to take the joy out of a new computer. You made a good choice. Enjoy!
