Hello, just wondering if anyone knows what the performance of DVD playback is on the iBooks. I'm getting the 600MHz G3 w/14.1" screen model. Should this be able to play DVD's back without a hitch? Does the iBook come with the DVD playback software? Thanks. P.s. Sorry for all the Mac questions in the last two days...just being a first time Mac buyer, these are things I would like to know which I know nothing about. I've been using PC's for years and years and years.
