In using the Apple Watch day to day, I'm also annoyed that audio playback controls — what I would consider a fundamental feature of the watch — are buried. If you're listening to, say, a podcast, in order to pause playback you first need to move your wrist, press the home button, swipe to the Now Playing "glance" (the term Apple uses for app screens), tap to activate the glance, then tap again to actually press pause. That's five steps for something that should be two at the most. – Pete Pachal, Mashable
If that means adding more physical buttons then so be it.
Dear Apple, Turn the Apple Watch Into the iPod of My Dreams
