i have two Rhodium's they one for work and one for play, they use an sd card so i can quickly change between the two. it also has a very good 2" screen that plays avi (xvid) files at 24fps opposed to the 12fps of amv players. it also has a user defined EQ.
Battery is about 3 hours Continuous music playback but i have orderd a ipod nano battery that is 900mha. not sure if it will fit yet though but it was only a few pounds
