most truly memorable computer i ever owned was the Titanium PowerBook G4, and my model had non-glare glass.
no screen has ever been more enjoyable.
however, i was not a creator. and the PowerBook was not an iPad.
the usage case scenario for an M4 iPad with nano glass, that heavily markets its use of Tandem OLED, and super bright, high NIT etc etc, but making that very same screen non-glare, which will make those sharp blacks less black and sharp...? maybe the fake-creator who sits with his/her back to a bright window all day but wants the most expensive machine money can buy...?
i cant even begin to imagine what an apple Pencil does to it, if on the other side of your mouth you are telling people to only clean it with the special polishing cloth.
of course, we can expect that the technique to create my Titanium PowerBook G4 non-glare glass, and, this technique that is used on an iPad of 2024, is probably completely different.
but what is the case use scenario for this combination?
