Instead of me manually entering my weight & body fat, how about having some integration with the Withings wifi scale?
Here's the API link

I have both the Tanita and the Withings. Bought the Tanita first. Hate it. It is clunky, the plastic feet fall off easily, it is meant to stay in one place right next to your computer (in my office?? WTF). Got the Withings, LOVE it. Can be anywhere my network can reach (Bathroom where it belongs). Solid piece, no feet, no errors, and works with so many apps without any fuss. Unfortunately, I recently switched from Suunto to Garmin 910xt (and in love with the device and GarminConnect) and now want this data in my Garmin Connect account. I was going to sell my Tanita but now i am going to have both? Doesnt make sense. Open API, please Garmin, do this. Get into the era of Wifi and openess, it is here, don't fight it, Tanita is a dinasaur as far as i am concerned. You should be a leader and not be held back!
