Nike's FuelBand. Hmm...

According to Nike, you wear your FuelBand during the day to track your steps, calories burned, time spent exercising, etc. But more important, it also calculates something called "NikeFuel" using another something called "oxygen kinetics," which tells you just how active you've beenwhether you've been dancing, walking, playing basketball or sippin some Gin & Juice. But at $150, I'd rather have their Sportswtch w/ GPS for $50 more. Just saying.
