So, I generally don't share info about Health or Fitness products, but this one is totally worth an exception because it can attach to your network!
The Withings Wifi Body Scale is a normal scale with the added ability to attach to a wireless network and upload its data to a central server to be viewed after the fact. It's bit on the pricey side when compared to a non-networked, traditional scale that simple provides your weight. However, it is quite comparable in price to other digital, sleek looking scales that provide BMI and other information.
This thing can also track multiple users automatically. Just step on and it should recognize who you are. The whole family can geek out together while tracking their vitals!
Got an iPhone or iPad? Then this is for you because there is a Free iPhone and iPad App that goes with this scale. Available in the iTunes App Store to monitor your vitals on the go.
