I have to think that Pebble, and most other smart watches, are going to get crushed by the Apple Watch. iOS has an amazing ecosystem of developers that enhance the value proposition of owning iOS-based products to the point where literally no one can compete. People argue over the size of the smart watch market, but whatever it is, Apple will take a huge chunk of it. I see Pebble faltering before the end of the year, so I wouldn't want to buy one at this point.
