I purchased the 4GB version along with a 16GB Micro SD card - so 20GB memory for about $55. I like the interface - the navigation is simple and consistent between menus. The documentation is not really complete as the music content on the external card can be accessed from the Music menu - not just the card menu. The only limitation I've found is that playlists can only be stored on the internal memory.What I really like though is that I can select MP3 folders from the external memory card and then select shuffle at any level. So I can shuffle the entire card, a folder for one artist, one genre, etc. Or I can select one album and play or shuffle that. It nearly eliminates the need for playlists which is great since the internal memory is somewhat limited.Sound is good in the car and with earbuds. For music and other audio content this little device is a great value. 

Question: How is the player?
