I have two possible deals going on right now, and I'd appreciate any advice on which is the better deal... 1.) 12" G4 Powerbook - $500 1.5 GHz Processor, 768 mb RAM. 2.) 17" iMac G4 - $350 1 GHz Processor, 1 GB RAM Thanks so much! If you have any other comments on if either of these is a bad/good deal, please forward it along!
