The Fitbit ($99) is a pedometer on steroids. Clip the tiny device to you and it counts your steps, monitors your activity level, and tracks the quality of your sleep. Using the same 3D motion sensing technology as the Nintendo Wii, the creators of the Fitbit hope to turn everyday activities into a fitness game. The gadget uploads your activity stats, including calories burned, wirelessly to the web.
