I was thinking about picking up a G3 iMac for my Mom. I'm a relative newbie, and I was curious about how it will run with OSX. All she'd use it for is surfing the net, email, and playing card games (anyone know of any good ones for OSX btw?). What would it's performance be comparable to in wintel land? And what's the range in performance like from 233 MHz to 450? Thanks for your help!
