iRiver has crammed the iFP-180T with more features than seem possible, considering its small size. With 128MB of integrated memory, the device can hold about four hours of music, depending on your favorite bit rate and audio-file type (the iFP-180T can handle MP3, WMA, and ASF formats). A built-in FM tuner provides auxiliary tunes when you're tired of listening to your own music, while a voice recorder takes dictation on the go. You can even use this function to record live FM radio, which you can later upload to your PC.
