Microsoft Band - $200. Activity tracker, smartwatch, lifestyle assistant. I'm intrigued by the concept but I want to know battery life and how you charge it. It tracks so much: heart rate, sleep activity, built-in workouts, etc. But it's all useless if I have to charge it every few hours. I like the form factor, though. Works for Windows mobile, Android, and iOS
Microsoft Band - the first device powered by Microsoft Health, helps you achieve your wellness goals by tracking your heart rate, steps, calorie burn, and sleep quality. It also helps you be more productive with email previews and calendar alerts - right on your wrist.
