Samsung Galaxy Gear

The most feature-packed watch available – which currently works with only Samsung's Note 2/3 and Galaxy S3/S4 – has a customizable 1.63-inch LED touchscreen that shows time, date, and weather. But the real fun starts when you answer a call and speak to your wrist. You can also dictate texts and snap photos with a 1.9-megapixel camera. It works with roughly 70 apps, including RunKeeper, but the Gear is crippled by slow speed and a two-day battery life. [$300; samsung.com]
