hi guys...i have never used os9 since making the switch 3 years ago. Do i really need this on my powerbook G4? How much memory is it using, and if we all agree i can uninstall it, how do i go about doing so? I don't want to mess up my machine, but if it is a good amount of memory, i could really use the space. Can you all advise? thanks ps- hope this i was a good place to ask this question.
