If you are considering trying out Audible they are offering a free audiobook download with a free 30-day trial to give you the opportunity to check out their service. Spybrary will earn a commission for every sign up (even if you do not renew.)
Personally I am a big fan of Audible, in the past year I have listened to 36 books and novels. There is no stigma in listening to books, if its good enough for Professor Penny Fielding Peter Morgan and Matthew Bradford its good enough for me!
