With all due respect, dolstein, I think the G3 line will soon be dead. Once the iBook goes to a G4 there is NO TURNING BACK for Apple to use a G3. Apple didn't do that with the eMac, and, IF there is an eBook, Apple won't do it for that, either. It is going to be G4 and onward.
Although Jaguar runs much faster on a G3, you still lose a lot of time in many applications, which require a G4. Examples would be iTunes, iMovie, FCP, the list goes on. Even a 2.0GHz G3 will not satisfy many consumers with big time video editing, when there is a dual 1.0GHz G4 (soon to be upgraded) to roam about.
Plain and simple...once you go G4, don't think about the G. be4.
