This is not true. I have a glossy MBP from late 2006 and NOT once has glare ever been a problem...
Glare is never the problem. There seems to be a huge disconnect here. People who complain about the glossy screens are NOT complaining about glare and reflections.
The problem is color fidelity.
What's that? It's the thing you need to have if you are creating content for print. Graphic artists who are designing things like food containers or junk mailings or album covers or what not like to be able to preview their work on-screen. Photographers who make prints like to do the same.
Consumers who mostly use their Mac as a media player like the punchy colors but if you create images. Well it's like an audio engineer trying to work out a mix and using a boom box as a studio monitor.
Glossy screens have the effect of exaggerated color contrast and saturation. It's NOT about glare and refections.
