I’ve always felt that the flattening of Apple’s user interface
that began in iOS 7 was as much a strategic move as an aesthetic
one. Our first reaction was to realize that an unadorned interface
makes it easier to focus on content.
But with this new display technology, it’s clear that interfaces
with fewer pixels have another advantage. A richly detailed button
from iOS 6 would need more of that precious juice strapped to our
wrists. Never underestimate the long-term benefits of
Apple hasn’t officially stated that Apple Watch uses an AMOLED display, but it’s sort of an open secret. The other thing is, regardless of the underlying display technology, iOS 6-style skeuomorphism would’ve felt downright gauche on the watch. I don’t think iOS or OS X needed to eschew skeuomorphic textures, but Apple Watch did.
