I recently got an ipod and it's a major part of my recovery right now. I listen to it in work to make my job more tolerable. I have downloaded all the AA speaker tapes from itunes and this:
Dharma Punx - MP3 Talks . I am not a buddhist or in AA but there is really useful stuff on these. Oh and I download all the BBC comedy podcasts just so people think I'm nuts when I'm laughing to myself
