This has been beaten to a pulp in the MacBook Forums. The simple answer is that if you are a professional graphics person, who needs the color accuracy, and have no access to an external display, then you really need to go with the matte. The glossy basically saturates the colors, making them more vibrant and ... I guess you get more of that "POP" from your screen. I went with the 15" glossy despite the fact that I do some color- specific editing b/c I have a 24" monitor I can calibrate to my heart's desire. To be honest I like the glossy for general use, and I think the look of it is nicer than my large display.
