Runners need an ipod with no movable parts, which might be damaged with movement,

so look at flash-based MP3 players. Many include a radio tuner and voice recorder and some even support SD cards (Secure Digital), CompactFlash, SmartMedia cards, or MultiMediaCards, relatively inexpensive memory cards also used by digital cameras and some PDAs.

If you already use a memory card for other devices, buy a player that supports the same type of memory card, and use your storage media with all your devices. Popular flash-based MP3 players include the Apple iPod Shuffle, iRiver iFP series, NOMAD MuVo, and Rio Forge Sport.
