so i am considering buying a powerbook G4 on ebay. heres the stats: 1.67ghz powerpc G4. 2gb pc2-4200 ddr2 ram. 15.2" 1440x900 screen ATI Radeon 9700 80gb HDD 8x DL Superdrive built-in airport. Illuminated keyboard. 1 firewire 400, 1 firewire 800, 2 usb ports. 5.6 Pounds. Up to 5.5 hour battery also comes with: Mac OSX Leopard Microsoft Office 2004 CS2 Incase 15" case applecare until 12/09 Now my dilemma (try to keep it concise). I am going to buy a notebook for college which starts september 22nd. I was going to buy a macbook (dont necessarily need the pros capabilities--save some $) but I want to wait for the revision (I have read extensively about the possibility of redesign for montevina) but if the revision doesnt come until september/october i will need a notebook for college. i would sell it and buy the redesigned macbook. should i buy this as a backup or just buy a current macbook? i mean this seems like a freakin sweet deal...help?
