Watch for the inevitable explosion of videos with important content (like "Apple sucks") placed in such a way that it will be hidden behind the notch.

Yeah, some bizarre asymmetry there. I'd have preferred they just shrink the top/bottom bezels, similar to the Galaxy S8 or LG's V30. I can't see "the cutout" aging gracefully.

I wouldn't be surprised if you could double-tap to zoom out, like when watching 4:3 videos on the current iPhone.

They said that you CAN do that, the screen is wider than 16:9 so normal content will already be presented with black bars on the side anyway and you never have the notch covering content .

I'm sure they're going to let you make the status bar black to make the notch seamless.

Charitably, I assume if you’re holding the phone with no bezel, your thumb has to cover up part of the screen anyway. So it’ll cover that space.

Otherwise that’s the dumbest design decision I’ve ever seen them make on the iPhone hardware. It’s worse than the protruding camera that they STILL have.
