6. Nike Fuelband
Most people that have one of these will agree: it's essentially the calculator watch of our generation. A mixture of watch, athletic signifier, and hyped item, the Nike FuelBand struck a chord with people who actually use it to track workouts and folks who just liked it because of its initial scarcity. One thing's for sure: they've definitely overtaken the once-ubiquitous LIVESTRONG bracelet, and without any role models with skeletons in the closet carrying the FuelBand's flag, it's hard to see this product's fall from grace anytime soon.
