I'm a 20-year Mac user, and (amazingly) getting my first iPod (touch, 16gb) next week, as part of the back2school. My new MacBook's arriving about a week later, since I customized to the 250 drive. Anyway, I want to use the iPT right away (naturally), with my current iBook G4, putting 2.0 firmware on it, some apps, and everything else. When my MacBook arrives, and I start syncing it with that, is it going to wipe out all the apps & stuff? I've done some searches here, and it seems I could just drag and drop music and movies at first, (and sync later), but I don't want to spend a bunch on apps if it locks me into this iBook. And any photos will be wiped out with a sync to a new machine, right? Sorry, but this is a tad confusing, with different rules for different files. Anything advice about using multiple computers? Thanks!
