Their main supposed advantage, that they mitigate glare, is just false. With a glossy screen you get a small point of reflection. Matte attenuates it just a tiny bit, but never enough so that is not bothersome. You can usually tilt/angle your screen to fight glare, but matte makes it harder because the glaring spot is bigger/more diffuse. Also, higher brightness is one of the things that fight glare the most and matte reduce it a lot!
Mobile phones, the devices we carry outside the most and should be most susceptible to glare issues never ever come with matte screens! How is matte even still a thing?
