The Fitbit Tracker contains a motion sensor like the ones found in the Nintendo Wii. The Tracker senses your motion in three dimensions and converts this into useful information about your daily activities. The Tracker measures the intensity and duration of your physical activities, calories burned, steps taken, distance traveled, how long it took you to fall asleep, the number of times you woke up throughout the night and how long you were actually asleep vs just lying in bed. You can wear the Tracker loosely in your pocket or clipped to your clothing, even bras.

It will be priced at $99 and will be available in December or early January. The device will sync via wireless anytime you come within 25-50 ft. of the station base. It will then upload the statistics to your account on fitbit.com and your statistics will be tracked there. The access to the website is free with the purchase of the device.

I might be trying one of these. Looks pretty cool.
