Well yeah but when was the last time anybody observed something completely absent of light? Even at night theres the moon so unless you've locked yourself inside of a closet with no light whatsoever it's pretty pointless. I think people are into this black stuff because it's the geeky thing to do and talk about with no realworld benefits. Even outerspace isn't completely black. When was the last time someone entered a black hole?
It's more than their (plasmas) ability to generated a "blacker black" they can also resolve a greater range of blacks. This means there is a definite difference between how an average LCD vs. and an average plasma resolve dark scenes in movies and even games. Shadow detail that is present in the plasma picture is just missing in the LCD picture. This is a very real occurrence and seeing a noticeable difference between how an LCD or plasma perform on these types of scenes doesn't require that you lock yourself in a closet.
LED backlighting + local dimming is the answer to this problem on LCD, but it is not fully developed yet and has still only seen limited adoption. When more manufacturers adopt this technology, the technology improves a bit more and the prices get more in line with plasmas LCD's may be able to push plasmas out entirely. Not there yet, though.
