Fitbit Aria Wi-Fi Smart Scale

Using a Fitbit to get in shape? Then odds are you're also watching your weight — so why not combine the two with the Fitbit Aria Wi-Fi Smart Scale ($130)? This high-tech bathroom floor-dweller tracks your weight, BMI, and body fat percentage, automatically uploads your stats to Fitbit.com, where they'll enhance the data from your Tracker, and automatically recognizes up to eight users so it won't be getting you confused with other members of your household.
