can anyone give me the specs. on the previous generation 15" powerbook... What I really want to know was if it had gigabit enthernet, pc 2700 ram, and firewire 800? Also how big is a difference between 1ghz and 1.33 ghz G4? What really makes me want it is the graphics card, I like ati much more than Nvidia. Both will cost me the same... and I would be buying the 15" through the apple special deals section.
