Yeah if this thing had a bluetooth headset it would be perfect. Even the mock up of the watch is something I would wear just as a watch. for the 25 and under crowd that's not a bad look. That coupled with it's small size, color touch screen, a different music interface than Itunes, workout apps, and being completely wireless would make me a costumer. From the mock up it looks like you might be able to remove it from the watch as well which would be nice when you just want a music player as well. The idea has a lot of potential and is way better than anything currently out today.
