I've waited for about 3 months for the mbp update, but then i saw the prices on the old powerbooks and wondered if it would be smarter to just buy one of those (12" or 15") for school, and an iMac as desktop. It will be the same price. Are there anything that i should know if i buy an old powerbook? Is the 12" as heavy as the MBP 15"? And are the PB 15" much heavier than the 15" MBP? I also noticed that PB doesn't have a webcam build-in. All help is appreciated! Sorry for the bad english, im from Denmark. Btw the price will be (in US dollar): 2764.56 $ which is the same price the low-end MBP is in Denmark !
