Hi, if the 15.4 alu books come out before August I will be very interested in purchasing it for college. I'm probably gonnna use the ADC purchase program, but I was wondering if they still add sales tax even though you're purchasing online. Also, how much does apple charge for shipping? If the price still becomes steep due to tax and shipping I'll probably go for a centrino laptop from voodoo. Thanks. I hope I get positive feedback. I really want the powerbook,but my dad is only willing to spend so much.
