I am not an Apple fanboy, but I do believe this “watch” will be a huge success. What you need to understand is that this is not a watch. It is a peripheral device that both expands the utility of the iPhone and decouples some features from the phone itself.
While the technology is still in its infancy, all it will take is a couple of good apps and it will be hugely successful. And since the best way to make a great app is to steal it, I would suggest that you sell your FitBit stock while you still can.
Fitbit will die.
My S5 does what that thing does.
I have two fitbits and haven’t worn em in a year.
