Nike has announced the Nike+ Fuelband which gives iPhone users in-depth information on their daily physical activity. With development assistance from the likes of Lance Armstrong, Kevin Durant and Carmelita Jeter, the Nike+ Fuelband is able to keep track of your daily physical goals using a built-in accelerometer.
