Ok... I am going to buy a PB this week if/when my local (michigan ave) Apple store gets units back in stock. I am debating between the stock 15" superdrive system and the ultimate 15" pb system (as called by the apple store - It has 1 gig mem, 128 meg vid card, 5400rpm HD). There is a $500 price difference between them, do you guys think the real world performance difference is worth the $500? I want something a bit more future proof than not, and that is what is pushing me towards spending the extra money. With the educational discount, the ultimate clocks in at $2799. Opinions? I plan to use the system for school with some light gaming, light vid editing, and the rare VPC 7 use. Thanks in advance!
