Dude. This is not rocket science. The glass sits between the bare TFT and your eyes. Lots of other displays have a piece of plastic here instead of glass.
It doesn't, I am ~90% certain the LCDs are used in other laptops as-is.
Most glossy 'color accurate' CRTs from back in the day had some pretty hefty antiglare films in them as well. You calibrate for this stuff, and it should come out really accurate regardless.
The reason why matte screens used to be preferred (before everyone drank the kool aid), is that
feel static. Unless you have some very intense sunlight shining down on you, the matte screen will be more comfortable because you can move around without the contents of the screen changing.
I know about the glass on the iphones being quite strong (it can scratch, I've got scratches on my ipod), but MBP screens are
much bigger. They don't have the same structural integrity, lol!!!!
One more thing to be said, is the pics I've seen that make either look bad are places you really shouldn't be using an LCD anyway. Outside in direct sunlight? You're not going to have color accuracy on
anything. For starters, the backlight washes out and you get a greenish shade from everything on the screen. Doesn't matter if you're using a matte or glossy laptop then, and the matte one may still be preferable because you're not seeing the sun bounce off full power into your eyes.
How would I know? I have a lot of LCDs and some are matte, some are glossy.
I really think people should go with what they feel happiest with, though. I DO have to admit, glossy screens are a lot easier to keep clean. However, they show dirt a lot easier too! XD
That, and matte laptops just look better to me.. >>
