there is this powerbook(15in) G4 on ebay that i've been looking at. i've also been looking at the macbook. the upgrades i plan on doing to the macbook are as follows: superdrive, 80gig HDD, 1gig RAM. the powerbook's specs are as follows: processor speed 1.5GHz, 80 gig HDD, 1gig RAM. the powerbook is going for 1000 dollars(american) w/shipping, about 1020. the macbook setup is going to cost me about 1500. do you think the powerbook is a good deal, or do you think that with the macbook being intel based make it more desireable?
