So not only big speed increase from 2g, but now reports of a new improved screen: http://reviews.cnet.com/8301-12519_7-10351282-49.html entire Cnet review of Touch 3g (4.5/5 stars): http://reviews.cnet.com/mp3-players/apple-ipod-touch-third/4505-6490_7-33770783.html?tag=mncol;txt
there is not enough of an improvement for me to upgrade from a 2g touch, and the functions they added are battery hogs like voice control
