How to listen to Audiobooks without a smart phone. UPDATE

I use a Sansa Clip, and/or clip zip, very reasonably priced, I have been using it for years, and I use it specifically for audiobooks.

You can only save one bookmark at a time with the factory firmware, but it is very easy to put on a firmware called Rockbox, which gives you more options, and you can save multiple bookmarks(which is a must have for me so I never lose my place.

Rockbox is free.

Would never use anything else.
