Hi all, I'm a PC user since forever, but someone a few doors down is getting rid of an old Power Mac G4 (from the label on the back). I have never really used a mac besides when I have to, as a linux surrogate for research. I wonder, should I even bother with it even if it's free? What can you do with such a machine? Garageband? video editing? or just web browsing, and that's it? Can it handle the latest OS X (?), which I assume it will need? Thanks!
