She's getting this for Christmas. If she won't even use 32GB there's not point in getting 64GB. The $100 her parents save will probably be used for something else for her.
I can not believe the advice being given here. If you can get any size of Touch why not get the 64 gig version. . . . since it is a gift go for the larger capacity so what if it isn't filled up. Is is a crime to have unused space on a flash drive?
It's rude and inconsiderate to get one's parents to spend money on something (an extra 32GB) it if most likely won't be used. The argument "You're not paying for it so get the 64GB even if you won't use it" is disgusting, frankly.
