I'm going to Penn State this fall. I'm thinking about waiting for Rev B's to come out. They are due (according to the buyer's guide) in July or so, but there's no guarantees. I'm happy with a 15". I can't imagine Apple upgrading the MacBook that much for Rev B...a processor boost and 20GB HD capacity boost and thats all? So I'm just thinking that maybe I should just buy it early. I have the money now, so thats not an issue.
