Yamaha MP3 Player's Got Rhythm

Looks like Yamaha's offering a little sporting competition with the Nike + iPod. The $300 BODiBEAT has an accelerometer and a pulse monitor, and can transfer your statistics to your computer -- and you won't have to buy a new pair of shoes.

But there's more for those of us that are musically inclined. The BODiBEAT uses the accelerometer and pulse monitor to change the music playing so that it corresponds to your running speed. Alternatively, the BODiBEAT can create tailored workouts by playing music that gradually increases and decreases in tempo as you warm up and cool down.

The only flaw in this concept is the player's measly 512 MB capacity. For $300 you couldn't spring for a little more NAND, Yamaha?
