Summary
Sony's HMP-A1 media player is tiny, fashionable, and surprisingly useful. Anyone considering the A1 should first consider how they will get video content, and what they will do if that method is shut down. If that doesn't faze you, you'll enjoy one of the first PVPs on the market. The simple, straight forward interface will appeal to many first-time users, as will the overall build quality and aesthetics. The battery life is acceptable, the screen bright, and the software simple to use.
The Sony HMP-A1 could have been the video iPod if it weren't for the requirement to convert the video and audio files into a different format, which makes transferring files an annoyance. At a whopping $700, the 20GB A1 is vying for customers who would consider multimedia intensive PDAs, portable DVD players, and higher capacity digital audio players. If you're a fashion conscious commuter, the A1 is sleek, small, and offers great picture and sound quality. Just don't forget your headphones.

Operation of the A1 is so simple that many intermediate or power users may even be discouraged by its use.
