Okee Dokee, this is the last glass vs matte thread I will ever post in. I used to have a matte MBP. I now have a glass UMBP 17. I used to say that both gloss and matte had their pros and cons because I had passing usage with gloss and glass screens, but now I know: Glass is the best option. Here's why:
Modern LED brightness can power through nearly any reflection. Its much more difficult to power through matte because instead of spots of brightness here or there there is a wash of light refracted over the entire the surface of the screen. With glass you may have some spots on the screen that are useless in direct sun, but on the matte the entire screen is made useless. Even in a bright room facing away from light, matte washes out.
Matte screens are textured to make them matte. People bitch a lot that the glass screens over saturate colors and contrast. That's totally wrong. Matte screen's texture subdues colors. It also makes the image less sharp because of the texture distortion. The intensity of the glass image is not some trick of the glass, its the lack of surface texture distortion.
There is no reason not to have a glass screen when dealing with color reproduction. I've worked in digital photography, print, and web animation. In photography and photographer worth his salt prints on glossy. Magazines are printed on glossy paper. Web viewers most likely have glossy screens. If you want to know, accurately, how people will see your work then glossy is the best way.
And, BTW, my work space is surrounded by windows and I have no problem with the screen. Its the best I've ever worked with and I've owned 21" Lacie and Sony Trinitron CRTs. This is the best. Thank you Apple.
