I'm starting college in the fall, and have started to look at laptops. I'm going to go with a macbook, and I was wondering if the Air would be fine for my needs. I'm probably going into economics, and would use office a lot. My only question is if I got the Air how would I install office without a disk drive? I don't watch a ton of movies, so a disk drive isn't needed. With free time I would probably use Aperture now and then. I'd like something that's light, but that has sufficient memory. I am planning on waiting until the next update occurs before I make a purchase.
