M.G. Siegler, 500ish Words:
Using the Apple Watch effectively necessarily means breaking some of those iPhone habits. [...]
In an interesting twist, this is why I believe Apple Watch is going to be easier for non-hardcore iPhone users to pick up. Someone new to iPhone won’t have all of this muscle memory to re-train. Some Apple Watch features which feel unintuitive to me may feel completely intuitive to someone who isn’t used to doing something a certain way on their iPhone.
I had a rough first 24 hours with the Apple Watch. It was seemingly one frustration after another. Then I realized I was trying to use the thing as I would my iPhone. And that’s simply not what this device is. It’s not an iPhone replacement, it’s 100 percent a complement. Which is why some of the initial backlash that you wouldn’t be able to use the device without your iPhone was not only misguided — it was completely backwards.
I think M.G. is right and I feel this is what some of the early Apple Watch reviews got wrong. After spending only one week with the device when their reviews were published, it's hard to imagine that reviewers had fully grasped what Apple Watch is about.
There are certainly some quirks in the Apple Watch UX, but these might not be so jarring to "average" iPhone users as they are to the power users.
