Are you satisfied with the performance of the older machine? Can you afford a new and faster machine? Are you willing to upgrade peripheral devices and software if you upgrade the OS? Do you really need OS-10.5 on your machine? Do you just WANT a newer, faster, more powerful, and prettier Mac system? For me, it was a test only. I could do it, so I did it! The slower G4 now has OS-10-5 on it and it hasn't had any problem so far, but I am keeping an eye on it for any odd behaviour.
