I have an Emac. I'm angry because the Ipods don't work with Panther. I don't think it's worth upgrading the OS, but if I was, which one would I want? Mine is 1Ghz and 768 MB so it meets the requirements for 10.5, but would it run better with 10.4?
I had the same setup till a couple of weeks ago - now I am on my whitebook1ghz G4 emac with 640mb ram & Leopard here. Runs fine.
