Fitbit's Aria WiFi scale tracks weight, BMI and body fat percentage (hands-on)

We might never know the untold number of people who bought Withings' WiFi scale for tweeting their daily weigh-ins, but it must have been an impressive enough figure, as Fitbit just announced something very similar. The Aria Wi-Fi Smart Scale tracks weight, BMI and body fat percentage, only instead of sending those nuggets to Twitter, it all goes straight to Fitbit's own site. For people who have never bought any of the company's products, this website will understandably be a revelation, but in fact it's the same place where Fitbit Ultra owners go to see how many calories they've burned. Even if you're a newcomer, the website happens to be quite engaging, though we suspect you'll get the most out of it if you also have a Fitbit tracker to tally your hours spent on the Stairmaster. In any case, we got some hands-on time tonight (sorry, feet-on jokes are lame), and we've got hands-on shots below to prove it.
