Why does it amaze you? It's an objectively bad design. Not only aesthetically, but functionally wherein content is cut off in full screen games, apps, photos, videos, etc.
No one really prefers the notch as I have explained above. If I gave you the choice of a full OLED screen without a notch, or one with it, you would not choose the latter. Apple wouldn't choose the latter.
The notch is the result of technological ambition, cut short by what we are currently capable of achieving.
If this many people are complaining about it, including Apple loyalists like me, that should tell you something. It's a hole in your display. It's a hole in your content. We've seen game controls cut off by the notch for goodness sake.
This may even be worse than the Halos that are about to be introduced to F1. And in that case too, there was another obvious solution (closed cockpit) that could have been implemented to better achieve the desired result.
At the very least, Apple should give users two display options: one with the notch, and one without like in the mockups (where the cell signal, time, etc. are white on a black background). That way, users can choose what they want.
