Mass Storage MP3 Players: Battery Life

When you have more than 100 hours of music on one of the new hard drive-based MP3 players, the battery life of the device becomes important. Currently, players like Creative Labs' Nomad Jukebox and SSI America's Neo 25 play between 3 and 4 hours on a single set of batteries. Look for a player that accepts rechargeable batteries. Otherwise, you'll end up spending a fortune on batteries if you plan to travel with the device.
