Had decided on the device because of the existing bookmark feature, unfortunately, does this adequately, although you can bookmark each song define but the player does not realize the related album / the associated playlist - ie> one calls the song or audio book file (in * .mp3 format) on, playback starts at the previously deserted place, but stops after the title, the next song / chapter will therefore not play automatically.
Thus, the function is useless for me and so that the whole player.
Operation via the touch panel is prone to error and the response of the player to inputs slowly.
