This player is very easy to use. Best way to transfer music for me is to use media player, but it is just as easy to drag and drop. Battery life is endless.
You can sort music in all the usual ways, including folders, playlists, artist, etc.
The video playback is also superb, crystal clear and most formats are recognised (not FLV, you will need a converter like prism to convert to wmv).
Quite what some mean by "not loud enough" is beyond me. I have a liking for loud music and I can't go beyond 20. If this isn't loud enough for you then you either have a hearing problem, or you will have one before long!
All in all, an exellent product
