This is one of the masterpieces out there. The music is delivered with supreme quality, so the unit must have got many things right! Usually the problem with similar units is that the earphones are so bad that they actually undermine an otherwise good player. In this one, the earphones are top notch. The capacity is decent; voice recording, fm radio/recording all work just fine. Reception of radio is a little problematic, but this is common in all units of this size. It is easy to manage; it reads ogg files; can be used with linux without any problems. The random song list not being really random has been fixed with the latest firmware update.The last word is that it is a unit that you will be proud to own.
