So after using my MacBook(Core Duo), I had to go back to my PowerBook G4 1.25ghz due to my MacBook having issues. I am assuming the PowerBooks used to be lightning fast when they released so what I'm asking is...How could I make it like that? Would Tiger be a better choice? What web browser is the best? TenFourFox lags a lot on my G4 1.25ghz and the ram is maxed.
