Hey, Long time w/o a post, but thanks for all the advice regarding PBs about two years ago... Anyway, I'm thinking about getting a new iMac (20" 2.0GHz), especially with the educational discount and now the $100 rebate that they are offering for the spring. I love my PB (15" 1.25G4 RevA), but part of me wants to sell it and upgrade before it becomes even more outdated than it already is. I do enjoy having the portability, but with school coming to an end I don't think it will be as necessary as it once was. Also, I really would like to enjoy the performance increase that the G5 brings to the table. Questions: Is the 2.0Ghz going to blow the pants of my PB? Is it worth, in essence, exchanging one for another? I know it's up to my usage, but what would you do? Has anyone made a similar switch? Any other comments/suggestions would be appreciated as always (and is anyone in the market for a used PB )? Thanks as always everyone!
