I have a 2 generation old iPod nano, the one before the fat one. I'm considering getting the iPod Touch but I'm trying to justify the purchase to myself. Do you have to pay anything to go online with it or is it as long as you're in the vicinity of a wireless network you'll get online? Will the sound quality be better than a couple year old iPod nano? Has anyone upgraded from a nano that was still functioning? Sorry but I guess I'm looking for some reasons to go for it!
