I have no logical explanation for it, but I am a PPC diehard. I love running my 23" ACD off a 12" PB G4 1.5ghz with 1.25gigs of ram. However, is it slowing down on Leopard. Even with Dashboard disabled, I am getting in trouble when i have multiple windows open. So, of course, what I want is a two year old Powerbook G4 15 INCH 1.67. It can only take 2 gigs of ram, tops How dumb is this? I don't want to go intel, it is just some girly weird thing, i can't explain it. How much will I be limited by two gigs of ram?
