Fit Bit, $100 at Fitbit.com During the day, this miniscule gadget is meant to stay clipped to your waist or pocket while its 3-D motion sensor tallies how far you’ve traveled on foot and how many calories you’ve burned. At night, it marks the quality and quantity of your sleep. It then transmits all that data to the FitBit Web site where it’s transformed into charts and graphs you can neurotically analyze late into the night when you should be sleeping.
