New product/app (Fitbit) to passively track fitness and sleep
This is really impressive. I want to try it out just to see how well it works. I think it might be a pain to wear the sensor constantly, but for anyone with issues or goals for their sleep or fitness, it seems like a great product. Anything that gives you this much feedback, status, and info without having to enter data is awesome. its the Mint.com for your body.
