Hey guys, I just joined this forum because I plan to purchase my first mac soon. I'm starting college in fall and I want to buy a powerbook (was deciding for awhile between 12" and 15", settled on 15" but Im not sure how cumbersome it is going to be to carry it around campus, if anyone else has opinions on this decision, tell me please). Right now there is a promotional discount for SJSU which is about $120 off the educational price. I don't know how long this promotion will last so I want to buy the PB now, but I won't need it until three months from now. I checked mac rumors and it said average update was around 170 days, so will there be an update on the PB in the next 3-4 months and I should buy it then or should I take advantage of the promotional discout now? Thanks for the help
