Although the world already has a set of headphones that encourages you to work out, the newly announced Fitbit is just a hair more sophisticated. Designed to be worn or carried around in a spare pocket, the personal tracker is about the size of a standard flash drive and includes a built-in motion sensor to keep tabs on "exercise intensity levels, calories burned, sleep quality, steps and distance traveled." When it ships in late December / early January for $99, the unit will reportedly boast a fancy OLED display for quick readouts, and hey, it should even arrive just in time to complement your entirely meaningless New Year's Resolution.
