For those who have everything: Fitbit

You may think twice before scarfing down that cupcake, if you’re wearing the Fitbit. The finger-size tracker uses a motion sensor to wirelessly log your daily physical activity, measure its intensity and duration, and estimate how many calories you have burned, 24/7. The Web interface also helps you keep track of food intake, using a database of nutritional and caloric information on more than 50,000 common foods, from “Twinkies to tofu.” You might never gorge yourself again.
