I think some of you are missing the point.
This is not a matte vs glossy screen debate. Everyone's gonna have his own preference. This is however a debate for the freedom of choice - in this case the ability to choose a matte-finished screen as opposed to having Apple literally shafting glossy screens up our asses. I am in a particular group of users who believe in such freedom, which I'm sure alot of you would remember is something we used to have until only a couple of years ago during the introduction of the Al iMac where they start using the glossy screens.
For those of you who aren't particular with true colour representation or where your usage of the mbp is not dependent on that, having a glossy screen is perfectly alright. However, for a specific group of users, matte screen is imperative to their nature of work.
In a totally ideal world, where the glossy screen (a glass over a matte screen) is totally clear and free from any form of visual alterations, it will not impede true colour representation. In an ideal world mbp users who would not be troubled by glossy screens are those who work in a totally dark environment without reflective and glaring issues, but in reality how many of us work like that? Media editors, script writers and other professional users are constantly on the move in which they are always under the mercy of external elements which make a matte screen more suited for their use. There will hardly be a place with only a single light source outdoor where we can simply adjust the screen to avoid glaring and reflective issues as claimed by Tim Cook in the keynote. Although matte screen still suffer from glaring and reflective issues these days, they are less prone to happen unless in extreme lighting situations.
No one is saying glossy screen is useless, I'm just saying it sucks for my particular need.😀
