The reason for this is simple, for getting as much light to both eyes as with a 'normal' 2D image, they need waaay more brightness - which means a more accurate color-range, and to let it appear as smoothly, they need higher refresh frequencies, certainly for active 3D solutions. This results in a much better 2D-experience also... 3D tech is - as the article says, incredibly low-tech. Or you use polarized filters, or you need a way to synchronize your shutter-glasses and quickly alternate the images. Personally I'm absolutely no a 3D fan, but if I have to choose a tech, please give me shutter glasses. Provided your TV can handle the higher refresh frequency AND higher brightness levels, it's far superior. 3D with polarized filters give me instant headache and it looks like all the colors are bland and washed out, certainly in the movie theaters...
