A guy I know has been using his tired and true PM G4 MDD windtunnell for the past few years. He said he is ready to get rid of it (yikes!) in favor of an iMac G5. Not having a lot of cash on hand (he doesn't use the evil credit card thing) thanks to his refund from uncle sam he says he has enough to purchase an iMac G5 17" outright. But the thing he was wondering was how much better is the iMac G5 vs his old PM G4 MDD wind-tunnell? Not knowing anything about the PM G4 I wasn't sure. The only intensive work he does is video editing on an amature level. The rest is just basic stuff like web, email, word, excel, etc... He was considering upgrading his PM G4 MDD but felt that the iMac G5 is a better deal overall. Thoughts??? I'll pass them along to him as he is too lazy to sign up here.
