Sony Ericsson Bluetooth Watch

Sony Ericsson liked Fossil's idea for a caller ID wristwatch so much that they took the technology and re-designed it as the MBW-100 — adding the ability to control their cellphone's music player from the buttons on the side (play, pause, next track). The functions worked well during the demo, although we didn't get to hear it switch between music and call or anything. The watch is seriously sleek (it comes in silver and jet black), much fancier than the Abacus from Fossil. My only question is about the usefulness of the music player integration on $399 watch. Wouldn't this functionality be more appropriate for a sports style wristwatch?
