The glossy really boasts the colors, but there will be a glare with any fair amount of light and acts as a mirror half the time. The matte screen doesn't give off a glare, but the colors are not boasted as much as with the glossy.
My gf has a glossy screen,when your outside or somewhere bright if your not looking directly square on to the screen you cant see jack sh*t, go matte
Has anyone ever compiled a "most asked questions on MacRumors" survey? I'm sure this would be in the top three.
