"Nike today introduced its FuelBand wristband device, which is designed to measure a person's daily movement and drive the athletic gear company further into the technology world.
The FuelBand is designed to provide users with the time, the number of steps taken in a day, and calories burned. But the main selling point is a newly created fitness metric called NikeFuel, which is based off the rate of oxygen consumption and motion. The wristband will retail for $149, and is available on February 22 in the U.S., May 1 in the U.K., and the rest of the world in the fall."
