Not everyone just listens to music. Books are a terrific way to use your player as there is nothing to change and it just plays on until you stop it. I have 5 Sansa players now, starting with the E100 up to the E260R and just can’t understand why I can play Audible books on all of them except the E260R. Please make the player even better than it is and add support for audio books.
Please see existing Audible support thread.
