It's WAY too early to see whether people overall gain utility from the product. I'm not talking about personal anecdotes - I mean solid measurable evidence that the product changed the workflows of some people or businesses. That said, even Apple executives in charge of the Apple Watch explained that they first designed the product before seeing a utility for it - and that is it's fetal flaw.
With respect to the bolded text above, that's amazing. Please provide a link to that assertion.
Regarding "solid measurable evidence that the product changed the workflows of some people or businesses," can you cite organizations that collect such information and present it in the form of solid evidence?
For now, you will have to rely on real owners who are willing to talk about their personal experiences. I could talk about mine, as many others have done, but I suspect you would simply dismiss that as coming from a fan.
In the meantime, please provide that link proclaiming that the Apple watch was designed before seeing a utility for it.
