Engadget - There are generally two schools of thought on how to build a wrist-borne wearable. Either make a fancy pedometer that's supposed to stay out of the way, or go the smartwatch route and cram in as many features as possible. Then there's this weird no-man's-land occupied by devices like the Samsung Gear Fit and Garmin Vivosmart. Microsoft's $200 Band falls squarely in that latter category. It's not quite a smartwatch, but it's not purely a fitness tracker like the Fitbit Flex. The Band can pull in emails, text messages and other notifications from your phone. If you're using a Windows Phone, it can control Cortana and put the power of Microsoft's virtual assistant on your wrist.
