True.
Yep.
But I don't watch movies at all on my iPhone.
I don't read forums on my iphone.
That's one thing I do, do, light gaming, but I have my iPhone in portrait mode (always locked), so the notch is at the top of the screen, so I pretty much see it all the time, and it makes finger presses kind of hard on the top.
I do texting, phone calls, and email is pretty much the rest I do. I have some support tools for work, but hopefully I don't need them often, and I usually don't.
If I could change a setting to shrink the screen down to just below the notch, I'd change it in a heartbeat. (basically just make a bigger bezel at the top.) I'd give up screen real estate to get rid of it!
So yes, there are things I don't do on my iphone because it has a notch. Gaming is better on my android phone because the top is in play, but watch movies, not likely there either, the hole would bug me in that case.
