Query: Pros :   Great audio quality  Expandable Memory  Plays tons of audio formats  Customizable EQ and BBE+  Great battery life    Cons :  Terrible UI, probably the worse UI I've ever used  Resistive touch screen makes small movements difficult  Bricked 10 days after purchase  Proprietary USB cable  Scratches easily    Basically, if you just want a great sounding MP3 player with tons of audio options, go and buy the Cowon Iaudio9 or Sansa Fuze+.
