So what's the problem? The smartwatch isn't smart enough to be essential, to feel like a natural part of daily life. So far, it mostly duplicates things you do on your smartphone -- sometimes more conveniently, more often not. In most cases, it's just sort of a companion to your phone, losing most if its power when left alone.
So what's the solution? The watches — not just Apple's, but all of them — need to find lots more independent functions, ones that are consistent with always being on you and knowing who you are, without the nearby presence of a smartphone.
The key takeaway from this piece is how do tech companies create a need for smartwatches similar to one that is felt for smartphones.
