It boggles my mind why the thing that's meant to sit in one dark spot is protected from glare and the thing that's meant to be carried around is not. Is there any reason for this?
I understand that mobile phones have glossy screens to be more scratch resistant (although I'd still prefer a matte phone), but why laptops? Even MacBook Pro used to have a matte screen option 10 years ago but now all you can do is either buy an ugly screen protector or hide from the light.
On phones, capacitive screens use a glass layer. Apple extended the glass layer to the laptops because it looked better (probably because matte screens looked worse than phones). Before them the screens were matte. Of course, everybody copied Apple and introduced glossy screens, because when looking at a glossy and a matte screen next to one another (in a shop) the glossy will win. And of course, everybody introduced glossy screens without the anti-reflection coating that Apple uses (cargo cult), so it made everything worse.
There was a time period when you had to really search for a non-glossy screen. Now it's a bit better, you can find them, but the touchscreen ones will always be glossy, and I did not yet see an OLED without glossy screen (could be because they are more fragile, although folding OLEDs do exist, so it's not clear).
