Yamaha BODiBEAT MP3 Player Syncs The Music To Your Workout

The end of time when you dance to the tune is nigh. Behold the BF-1 BodiBeat from Yamaha, a MP3 player that changes music according to the pace of your exercise. With three different modes to choose from, the BodiBeat synchronizes perfectly with your moves and plays the right song with the right tempo, based on the onboard accelerometer. It can also double as a heart monitor and a normal music player when not working. Available later this year for $300 for a 512MB version.
