Which Will Be Better for Me, iTouch 4G or iPod Nano 6G?

iPod Touch 4g. I have one and I love it! Length wise it's about the same size as the iPhone but it's a lot thinner. It's battery last pretty long, as long as you don't turn it all the way off and turn it back on. Just press the on on top so it will just put it on stand by. The battery lasts longer if you do that
