Okeedokee, iPod newbie question:
My lovely wife just bought me a 20GB iPod, and I'm loving it. Holds my 10.5GB music collection (yes, all legit!) with room to spare. I have it synced to my G5.
Here's the deal - We're going on vacation for three weeks and I plan on bringing the iPod and my iBook... don't think the wife wants me schlepping the G5 tower with us

Trouble is, if I buy any new music while away, I think I'm SOL in so far as getting it on to the iPod. Is that right? If I connect the iPod to the iBook, will it allow me to transfer new music to the iPod - without erasing everything presently on it?
I'm not concerned about moving music off the iPod. Just importing new CDs on to the iPod.
