A billion years ago I had a Vaio TZ that had a glossy but still anti reflective screen. Used some kind of coating layers using the same principle as museum glass. Whatever happened to that? This was forever ago and it really worked pretty great, and I loved that machine so I used it a long time, and I can say I had no problem with the coating failing from wear or age either. You could get a reflection if you tried hard enough, but you never had a problem seeing the screen contents even in a glare situation, and I'd think that would be the primary concern.
