Rio Nitrus 4GB MP3 Player

Brutus to the mighty iPod Caesar is Rio with its new Nitrus MP3 player. Featuring 4GB of memory (132 hours of music), what separates the Nitrus from the pack is it quarter sized hard drive using Cornice technology. This allows the Nitrus to not only be about half the size of an iPod but improves battery life tremendously with over 16-hours of continuous playback per charge on its battery. A bit pricey, but for smaller form factor and better battery life, the Nitrus is the first real challenger to the iPod. The Rio Nitrus 4GB is expected to begin shipping in January for $249. www.rioaudio.com
