I'm trying out Leopard for the first time ever on my friend's iMac G4 and I'm impressed. One thing though is that the menu bar isn't clear on his 1.25GHz G4 (same as mine); that's weird. But the best thing I've seen so far is the fact that Back and Forward in System Preferences has keyboard shortcuts and in fact is set to the same as Safari so they work on the back and forward button on the mouse. It's the little things for me, really. I don't know if that's been mentioned, or if anyone else cares (el oh el), but I was always annoyed by that in pre-Leopard mac.
