Also from Abdel Ibrahim, an interesting take on Apple Watch not having a primarily app-centric interaction model:
From the Watch Face, you are able to see your Glances and
notifications. In order to see apps, you have to engage the
Digital Crown. This makes it seem pretty obvious that Apple has
purposely designed apps not to be front and center like they are
on iPhone. Instead, Apple Watch apps are mere repositories where
stored information can be pushed to the user in the form of
Glances and via Notification Center.
This may sound a little weird, and I think to some of us it is.
We’re used to apps being the focal point. But on Apple Watch, on
initial waking, they’re not.
