Well I agree that the glare can be a little annoying, I have to disagree with you on the underlined, because I actually take care of my devices and clean them.
Also, theres nothing more disgusting than a dirty matte screen to me, they just seem like magnets for dust which takes FOREVER to clean.
I am obsessive when it comes to keeping my electronics perfect, and while you have no way of knowing that for sure, my opinion is ALSO that the glossy screens show dirt and smudges 100% more than the matte.
