You can't get too far in a conversation about fitness trackers without talking about Fitbit. These tracking wearables have become the widest known brand in the category, and with good reason. This year at CES we're not seeing any new products from Fitbit, but instead we're seeing new ways Fitbit can be used and intent to make the new Charge HR band and Surge watch more broadly available to the public.

What sets the Fitbit Charge HR and Surge Watch apart from other Fitbit are the GPS chips contained within. These chips, along with some new sensors, allow Fitbit to create a category for more serious fitness folks. The Fitbit Surge also includes some basic phone notification support, for things like an incoming call or a text message. It creates a hard dividing line between people who want casual fitness tracking in a serious smartwatch, and those who would like a serious fitness tracker that plays nice with your phone.
