Then why do it yourself?
Glossy screens are inaccurate. Period. Why? Because they create the illusion of colours looking good. It has absolutely got nothing to do with calibrating the screens as it is all about that illusion, it's about your eyes and not the colorimeter (eyes are inaccurate compared to a colorimeter). On a matte display you might not even notice the reflection, on a glossy screen you see the exact reflection. Because you can see the exact reflection it becomes another picture on your display making it harder to distinguish all the information on your screen.
That would be impossible as the screen reflects light back to you causing you to reflect light back to the screen. In other words, because the screen is on with you sitting in front of it you'll get reflections no matter how you position the screen. And yes, this is also the case when sitting in a pitch black room. Remember that everything that gets hit by any kind of light will show up as a reflection on the screen. Glossy screens reflect a lot more light so even the smallest reflections will become visible. Matte displays don't do this, they only show the biggest reflections which you cancel out when setting up a proper workspace.
No you can't as you might need to move into a very unergonomic position. You might also not be able to sit down the laptop on something like a table causing yet another unergonomic position. In this case, matte is the best option as it doesn't require you to move.
Yep, exactly what I thought, comparing glossy screens to matte screens regarding colour. No they do not show colours differently, glossy screens just create the illusion they have better colours which they don't as mostly they use the exact same TFT panel as matte screens do. Also you can not have 0 reflections as everything that gets hit by light will be reflected. You just don't notice these kind of reflections. Matte screens have the same problem but since they are matte the reflections are very very minimal and very hard to notice.
Yep, if you depend on your setup than be sure to buy the proper gear. However, a lot of people really wished Apple would give people the option for glossy and matte so they can choose instead of Apple. With the iMac getting up to par with the Mac Pro this becomes even more necessary as a lot of business users are using iMacs (they don't have a lot of flexibility in setting up their workspace).
As the new iMac 27" is on par with the Mac Pro a lot of people are getting the iMac as it is a lot cheaper. Those people can also buy a second display and hook it up to the iMac via DisplayPort (Dell has great matte displays with DisplayPort). If you fry anything you'll need to replace it. With a lot of parts that means you won't be able to work.
Btw, glossy vs. matte is not a discussion about home use vs. business use but more about which one is the most ergonomic to use and mostly which one you like.
If a monitor has been calibrated for a colour temperature of 5500K it looks yellow because most of the displays have a colour temperature of around 9300K when they leave the factory. The 5500K screen seems yellow compared to a screen with 9300K because 5500K is warmer then 9300K. Obviously a yellowish display is not a flaw, it might be one
First check if the colours and colour temperature are correct, if they are and the colour is off compared to a comparable screen than have it replaced/fixed because in that case it's more likely a flaw.
