Track your physical life with the Nike+ FuelBand. The device uses accelerometers to track your exertions, and relays them to your iPhone and the web through an available iPhone app. You can set up physical goals to keep yourself moving, or you can just track your physical activity to see how you are doing in your effort to keep healthy. You can also keep track of things using just the band's LEDs, but I have to believe the interconnected options makes this a lot more interesting.
