I'm a college student with a few extra bucks. I recently upgraded to a MBP 15 with leather interior and heated seats, but it's huge and I don't want to be carrying a $2500 machine around with me. I carry my apple everywhere and need it to be portable. I use multiple browsers, word (like it's my job), excel, dreamweaver, photoshop. and vmware with win7 (not all the time but I want the option). I'd like some feelings from people who know better than I on what decision to make. I normally just go for the top of the line, but I could stand to save a few bucks if possible. I know I'll need 4gig on ram on an air. No music is kept on my apples and battery life is important.
