Nobody is UPGRADING their smartwatches because why the hell should I pay $350 to get a watch that has zero features above what I already have? When I had a Pebble Time it did everything I wanted then and the other pebble offerings were useless iterations that either offered a useless feature (lighter and shorter battery).
the Apple Watch 2.0 only really offers waterproofing. no real advances that people would dump another $350+ to replace their 1 year old Apple Watch 1.0
The android watches, well nobody has been buying them, they have always been the last place runners, but their new iterations are all useless. Zero advantages on the new versions.
The ONLY smartwatch maker not with their head up their ass is Pebble. 10 day battery life in the Pebble Time Steel. Apple could have doubled the battery life, Samsung could have doubled battery life.... nope, they are all stuck in the "ZOMG THINNER!" stupidity.
