i would wait, or buy an alternative product. i currently own a 3D 15GB iPod, and here are some things i hate about it:
cons.
1. the touch sensitive buttons truly suck. they basically make the remote mandatory. unfortunately, my remote has already gone on me - one channel cuts out. most likely due to a crack in the wire. a new remote isn't cheap. the new 4G pods will have the ipod mini buttons, so u can keep the pod in your pocket without it being on hold and actually skip track, play, stop, pause, etc. without having to pull the thing completely out of your bag/pocket/whatever, take hold off, and then select play options.
2. the battery life is dismal. i think the life of my battery after less than a year of use is down to about 6hrs. it's insufficient to daily outings without bringing along the charger to recharge it.
3. there's something else about it that i hate, but i can't recall at the moment.
it's super cool, but if i had to purchase an mp3 player all over again, i wouldn't buy the ipod. i'd opt for something nearly equivalent in size (hdd capacity and physical size) but with longer battery life and non-touch sensitive controls (no other players sport touch sensitive controls anyway). the touch sensitive scroll wheel is cool though, just not the buttons.
