Alright, I've finally decided that a 15" PB is for me. I can get a nice one from the apple store for 1799 with the edu discount or a refurbished one for 1699. But then the rumors have been swirling that they're about to update the powerbooks next week. But with no keynote, how likely is this to actually happen? Will the price difference be that much to make a difference for me? Should i wait?
