But if you're on the fence about which one to get, I'd go with the cheaper one. In a year or two, there will be some cool new iPod that she'll want and the one you're about to purchase will be more obsolete than the technology used to do Epcot's Lights of Winter.
You are very right. We are considering getting DD12 a new one. Hers is a little over a year old. Decisions, decisions. DH said to get her the 32 because it's only $70 more the day after Thanksgiving.
