and by unresponsive, i mean it lags. It lags so much it takes 0.5-1 sek to update the screen everytime i push a button. And it's unmoddable as far as i know.
the zen mx comes with 16gb and an sd-card slot, and the sd-cards are getting pretty big nowadays. However, i wouldn't recommend the player. The menus are unresponsive and the screen get scratched almost immediately.
