Alright, i'm going off to college in the fall, and I'm planning on getting a powerbook (either 15" or 17" - though i haven't written off the possibility of going desktop), but i don't have too much cash to burn. (Actually, i'll be getting it on loans if possible...) What would be the best time to buy? Will there be some pricebreaks anytime soon? Is there a cheaper place than apple.com? Help! Thanks mucho!
