I think you both are bringing up facts from 2009 era. Crosstalk does not exist on decent displays anymore. Cheaper ones, of course. You get what you pay for. Glasses have also come a long way. My active glasses weigh less than my lightweight prescription glasses. I don't have a scale to weigh them but I can assure both of you, weight is not an issue. Heavy batteries? Do you know how small and lightweight a CR1620 coin battery is? If you'd really like to make a real world comparison, hold your passive glasses in one hand and a pair of SSG 5150's loaded with that hefty CR1620 in the other. Lens stuttering? LoL. I think you want to feel good about your passive or something. Let me help you. Lift up your feather weight glasses and look closely at the pixels on your passive screen. See a row of black dots every other line of vertical resolution? Enjoy them.
