Acquiring Pebble could’ve been a good thing; integrating Fitbit’s activity-tracking tech in a smarter, more attractive device would have made for a compelling product. But instead,Fitbit is  loyal users already competing against cheaper options like Meizu’s H1 Band, and, as recent numbers show, it’s not pulling in great sales there either.  Pebble loses years of hard work and Fitbit gets the remnants of a company without the hardware   and the fan base  that made it a cult favorite in the first place.
