Fitbit Force ($130)

Fitbit got out in front of the wearable fitness craze early with the Fitbit Fit, but this year's Force is the company's best effort to date. It tracks your steps, calories burned, number of stairs climbed and sleep patterns, displaying this information in a sharp display. That's all complemented with a comprehensive Web interface and wrapped up in a comfortable, lightweight wristband. The downside? No heart-rate monitor.
