I'm thinking about picking up an eMac. The guy doesn't know what's inside the machine. What can I expect? I've been looking some YouTube videos and it seems to run pretty solid. It even did the Leopard intro video significantly smoother than my PowerMac G5 I'd like to use it for some light web browsing and video playback (not necessarily HD) Does anybody have one of these machines, and what can I expect from it? Thanks in advance!
