I'm actually feeling sorry for the people that got suckered into the "no reflections, must go matte" $50 matte option. Matte displays usually are dimmer and a bit blurry. The dimness problem may not be relevant due to the LED backlights. Also, matte displays aren't 100% reflection/glare proof, they simply spread the reflection/glare light arcross the display. So it's not 100% color accurate at all. The only true reflection/glare proof type of display is OLED, which is very costly; even a 3" panel (like Zune HD) costs $50 for the manufacturer. Any true professional would never use his/her notebook screen as their default display; they almost always have an external display.
I personally think reflections are overrated because I was using my uMBP at a college classroom. It was very sunny and there was a window-wall behind my desk. I saw reflections, but I wasn't focused on those; rather the notes I was taking. Unless you focus solely on reflections, glossy displays won't bother you. People tend to focus more on what they are doing, than to play lookout for reflections and glare.
