Ok, other than the fact that you're completely wrong about it being a reflection issue. Yes, there's a big illumination difference, what does that matter? You're not ever going to compete with the sun. Bottom line: you see mostly reflected light from the sun off your screen, no? Limit that issue and you'll have a brighter screen. Manufacturers are not going to make the screens any brighter, there would be no way to efficiently achieve that, even if they had an Archimedes death ray powering it, what would that do to battery life? Cheapest solution is in the glass.
