An artist friend of mine has what is essentially a white cotton muslin curtain that goes around their work area which keeps reflections down to near zero (without being in the dark) and only uses glossy displays. It would drive me nuts but I see the attraction.
AR coatings on touch screens are problematic because skin oils make visible marks, but on non-touch glossy screens they should be standard. Indeed, back in the CRT era, it was routine for high-end CRTs to be coated.
I have noticed that Apple is using a coated screen for at least one model of MacBook Air, but for some reason they don't seem to have fully embraced coated screens.
I was really against buying the glossy screen but the matte looks washed out compared to the glossy. If your display is around 60% or above brightness then you really dont have a glare issue.
And if you're using a laptop outside of a home/personal office environment (which laptops are presumably built for), you don't have control over lighting either.
For tablets and mobile devices which generally aren't used for working at long stretches, I guess I can see the appeal. But it's really strange to me that glossy is popular on machines people do use for long-stretch work -- and often in high-glare overhead lighting open-plan offices.
(And not only popular, but increasingly the only available option.)
The annoying thing is that it's nearly impossible to find a glossy screen on the market.
It has a lot of compatibility problems, and is hacky as hell. I doubt Apple would adopt this as an official/first-class solution to anything.
Solving "compatibility problems" is what Apple do best by requiring you have an Apple Mac Pro and an Apple Cinema Display and not supporting any other configuration
When I made an exception and bought a notebook with glossy display I regretted that a short time later. Glossy display? Never again!
