Impressive numbers for wearables. 'Connected' bands like Fitbit and Jawbone grew over 600% from 2013 to 2014. These have all the 'intelligence' and computing power in accompanying smartphone apps and are more or less pure data collectors. The 'smart bands' that come with own displays and computing power also grew strongly, but not nearly as much as the 'dumb ones'. Maybe its the price - or people prefer to take control of connected products via their smart phones.
