Withings scale
The Withings scale looks like a normal, albeit modern bathroom scale. It measures body fat percentage, displays BMI, and accommodates multiple users. What sets it apart is that it connects to your wireless network, and tweets your weight every time you weigh yourself, and sends all of the details (weight, BMI, body fat %) to the Withings servers, which you can log into directly to track things like your lean mass, fat mass, etc., or you can access this information through the Withings iPhone app (free). The Weightbot iPhone app can also grab data from your Withings account, if you prefer that app over Withings' own.
I gave my Withings-linked Twitter account out to a few friends and a co-worker, and I have to say that I am tremendously pleased with the results. Not only have I lost 20+ lbs in 1 month with ONLY a diet change (no extra exercise), but now every time I think about eating, I think about that scale and the fact that tomorrow, my weight will be broadcasted to those who'll hold me accountable.
The scale costs $159 from Withings directly, and you might be able to find a better price somewhere else. HIGHLY worth it for anyone trying to lose weight.
