Anyone here use/own a mac? I just bought an iMac off my company, G3-600mhz, 384 meg of ram (or so), installed with OS 9.1 and OS X (early, crappy version). I like the Mac OS, seems clean, easy to use. I was just wondering, what impressions others might have had with it? Can you really replace windows and all (or most) of it's functions with it?
