I think it's a bit of a silly question. I mean, do we need SLI/Crossfire? A good portion of computer users would say no. Do we need hexacore processors? Do we need soundcards? Who knows, but obviously somebody wants them. I personally have a Blu Ray drive that I use a lot. I use it to play DVD and BD. My internet connection is not up to the task of streaming HD content, and with data caps being brought in streaming might not be the best solution for everybody. If we didn't need/want them, they would die I think. That's how it is i think, it's like evolution by natural selection, the weak will naturally fall. Do you think Asus, Samsung, LG etc. would bother manufacturing them if people weren't buying them?
