What Grog said. I use my iPod Touch a lot. Moreso than my DroidX smartphone (which I can't stand), for Internet browsing, email, and music. I rarely turn on the p.c. any more. It's a do-it-all machine.
I don't have as much music on it as Grog, but can plug it directly into the new truck and listen to what I do have there (that may apply to podcasts, too, but I'm not sure.).
