The thing with the notch is that if you look at it purely from a design aesthetics standpoint it's ugly and an eye-sore.
If you look at it from an engineering stand-point it's actually a beautiful solution. Maximising the screen and doing away with useless bezels.
If you look at it from a usability stand-point, it's no issue at all. It literally disappears within moments of using it and you get the benefit of having extra screen real-estate. I especially like the blue navigation shape you get in the top left ear when minimising a navigation app, instead of a huge black bar you get on other iPhones.
The notch is here to stay. It will first become smaller as they are able to merge sensors, then it will become smaller as parts can go beneath the screen and finally it will all disappear when a camera can be placed behind the screen. Sadly, I don't see a camera behind the screen happen within the next 2 years. I always say, if you see how bad front-facing camera's are right now in comparison to the back camera, can you imagine how bad the camera will be when placed behind a screen.
