Got myself iRiver iFP 795 just yesterday, haven't got time to learn it fully yet. So, just several points :
- If you purchase iRiver iFP, do your homework and purchase one that has UMS firmware available . There are Linux tools supporting iManager-based players, but I'm personally inclined to think that working with a regular USB drive would be preferable.
- iRiver FPs play Oggs encoded with bitrate in 96K-225K range. No less, no more. Although, it may be some limitation of the UMS firmware, and the players may support a broader range of Oggs with their default one.
- I've yet to see some more stupid user interface
