Considering that the device is already settled in the upper class of the good Sony range at some things lacking. Audiobooks can the nice part though motivated to play but do not store where I left off. But as I read several books in parallel in reality, one bookmark per audiobook would be good. Other devices can without any problems! And now here's the - the Sony Walkman's can also just do not know that Sony itself. It invites an audiobook as easy podcast up and off you go. The supplied software Media Go was also helped design the trainee and is not really good to use and intuitive.
I have the part bought primarily to be able to hear MP3s on long journeys in the car and because I often the Radio trash can no longer hear. There is good and I would buy it again.
