Hi everyone, just curious - a friend of mine has a friend (how every good story starts, right?) who is looking to upgrade his imac and he wants to sell his current one. It's a 20" 2.66 c2d that has 4gigs of ram and he will throw in the wireless keyboard + mouse. Does that sound like a half decent deal? Or would you recommend ponying up an additional $300 for a new 3.06 imac? Hopefully someone with a better eye for macs can recommend if it's good or not * Edit - BTW it would be for my wife that doesn't really do much to tax the system - just basic programs, photos, facebook, etc. So having a powerhouse isn't all that needed.
