I also wear a watch in the form of the Nike Fuelband. It sleeps when I'm not actively looking at it, so the battery lasts several days. The clasp is also a USB connector, so it just plugs into my laptop when the battery gets low. 30 minutes later and im good for another few days.

I also frequently get complements on it because it looks like a sleek wristband until the LEDs light up.

I would love to see more wearable accessories go this route and conserve power until I actively look at or wake up the device.

If someone added streaming music or mp3 functionality that could pipe music to a Bluetooth headset, that would be something I would definitely pay money for.
