I'm interested in switching to the mac--but to start off I want to get a mac under 1000 dollars. I've been searching the net (ebay) for G4 Powermacs and Emacs...The thing i like about the powermac is how upgradable it is, the emac isn't..The Emac is an all-in-one machine, with powermac just being the tower..I'd be using this computer for video editing, maybe I will upgrade later in the future, but for now this is my first adventure in the Mac (video editing) world...
