Hello Well first let me explain the situation. I am part of a coop program at my university and this fall I will be attending my second work term. The company I will work for will provide me with a brand new laptop. Ok it will be pc but who cares comes with the job. What I want to to is trade my powerbook: 2GB DDR333 SDRAM - 2x1GB SO-DIMMs 80GB Ultra ATA drive @ 5400 rpm 4x SuperDrive (DVD±RW/CD-RW) 1.5GHz PowerPC G4 w/128MB VRAM AirPort Extreme Card Backlit Keyboard/Mac OS - U.S. English AppleCare Protection Plan for PowerBook (w/ or w/o Display)(until October 16th 2007) ATI Mobility Radeon 9700 Bluetooth Apple Keyboard and mouse Marware case Neoprene with pockets For a stock used G5 powermac dual 2.5ghz: - Dual 2.5GHz PowerPC G5 processor - 1.25GHz frontside bus/processor - 512MB DDR400 SDRAM - 160GB Serial ATA - 8x SuperDrive - Three PCI Slots - ATI Radeon 9600 XT - 128MB DDR video memory - 56K internal modem Both macs are used and the powermac would be traded with an individual, not a store. I was wondering if you guys thing it was a good deal. Also how much should I pay extra or should he pay extra? I am really bad with the value of Apple computers. Any thoughts will be gladly accepted!! thank you! P-S: I My work term might be 8 months and if its only 4 months I'll be considering a new mac portable for January.
