Query: Great features, great sound, great price

The sound is fantastic on this unit. A firmware upgrade provides excellent equalizer functions, as well. Among the many cool features of this player: AM/FM radio with a ton of presets, record from radio, record voice with the built-in mic, playlists, etc. I love it, and I use it all the time (it has flash memory, so I can bounce it around without a problem).Only negatives are:1) the only way to get music into it is through the iRiver manager application and2) the limited storage (256mb)3) the little earpads come off frequently--buy extras.Since I use this primarily when I exercise, the limited storage is not a big problem and, for the price, not enough keep me from highly recommending this great little player.
