I feel that this MP3 player is pretty small. The battery life is decent.
However, after I sync music to it, upon disconnecting from the computer, I find that it has a very annoying "Creating Library, which must be started with the hold switch off. Also, after this occurs, the player is fully powered on, instead of switching off after being disconnected. There is no option to disable this. Mac users may dislike this however, as when it ejects under OS X, it immediately remounts. This is not a big issue, as it is easy to simply pull it out. The screen is a fingerprint magnet.
As for good points, I liked that it powered off and on fairly quickly, much faster than my previous MP3 player. This is one of my favourite features. Also, it is not neccessary to use the bundled software under Windows, as you can simply copy the songs onto the MP3 player. You can also play movies on the device, however it's 2 inch screen limits its movie potential somewhat. The interface is also quite intuitive. The bundled headphones are also pretty good.
Overall, a product I would recommend.
