Fitbit

Ever wonder just how good you're doing on your exercise regimen, or just how much you toss and turn at night? Wonder no more. Fitbit ($100; late 2008) is a tiny wireless tracker that you clip onto your clothing to track your daily movements — including steps, miles, calories burnt, and more — that wirelessly syncs with the Fitbit website, letting you keep track of all your activities. It's like Nike+iPod for your life.
