Be careful - currently available Sansa Clip Jam and Sansa Clip Sport are not supported by Rockbox firmware. Supported versions are Sansa Clip+ and Sansa Clip Zip (and some even older models). Killer feature of Rockbox for me is possibility to change playback speed while maintaining original pitch. As most audiobooks and podcasts I prefer to listen on 120-130% speed.
