PHYSICAL UNIT: This is a very small (3 in. tall, 1 in. wide) and light (less than 2 oz. including the battery) unit. It has a LCD screen on the front which displays quite a bit of information, such as the name of the current song (which scrolls across the screen), the time remaining, battery life, memory usage, etc. This information is presented in a compact yet clear manner. The LCD had a back light feature that can be programmed to stay on for a set amount of time. The unit is highly customizable with an interface that is quickly learned. Battery life is about 9 hours on a singe AAA battery. Although this does not sound like much, remember, it is for a single battery.

MP3 PLAYER: The 64 Mb model will hold about 20 MP3s (assuming an average size of 3 Mb). The sound quality is very good. The unit has four folders (albums) to organize your music. Songs can be played sequentially or at random, and you can choose from several pre-set equalizer settings, such as rock, classical, etc. I don't have a lot of experience with MP3 players, but I am more than satisfied with this one.

VOICE RECORDING: I originally found this looking for a digital voice recorder. It does a GREAT job! For the 128 Mb model with no MP3s loaded, you get about 4 hours of clear recording time! The microphone picks up well and there is a level indicator so you know how strong the input signal is. There is a quick key combination that puts you directly into voice recorder mode, so if you are in the car and want to record a thought, you can do it without even taking your eyes off the road. There is one drawback for using this as a voice recorder -- there is no speaker, so you would either need the headphones or plug into an external speaker to hear playback.

ANNOYANCES: I have only a few minor complaints about the iAudio. (1) The small plastic protective cover over the USB plug is hard to get off if you don't have long enough fingernails. (2) You can't connect the USB cable to the player while it is in its carrying case. (3) The ear phones are comfortable and sound nice, but they fit loosely in the ear, easily falling out if you are exercising. (4) The software does rip MP3s from CDs, but it is not the most user friendly interface I have used.

While this may seem like a lot of annoyances, they are all relatively small, and don't diminish from the experience. Overall, this is a great product! I have used the MP3 Player and Voice Recorder extensively, and am completely pleased with my purchase. Note, though, I bought the 128 Mb version, and would suggest that or the 256 Mb version.
