So I just bought myself my first PowerBook G4, after my iBook G3's screen gave way , but I'm excited none the less. It is shipping with a clean version of Tiger, and is equipped with the max 1.12 GB of ram, but I am wondering if I should upgrade it to leopard or not. I have seen several owners on other forums say it runs particularly slow, and that Tiger is the best way to go. Any opinions? Edit: It should arrive Tuesday - Wednesday this week.
