Um lazy, as I just explained, yes it does have w processors, and yes that means one CAN be used for each screen, but nothing would be hindered at all if they just had one big screen and, for example, split the work load for the top of that large screen to one and the bottom to the other. And um, calculating stylus positions takes a very small amount of work. Also, just because there are twice the number of potential positions doesn't mean that would be twice the work load. It would actually be pretty much the same, just with more addresses. It's not that the screens each have their own processor lazy, it's that the system has two processors and it also happens to have two screens. Trust me on this. I've seen heavy 3D on both the top and bottom while the alternate uses the weaker 2D. I've also seen light 3D done on both at the same time. I also happen to know something about programming myself I'd say, so I'm not just making all this up.
Just trust me when I say that the duel processing, while it does have some advantages, is neither needed for nor needed by the two screens. And yes, every single thing you listed COULD be done with just one really big screen.
One final thing. The two processors are not completely independant. Even though they can each be assigned the tasks of working out really complicated things that need exclusive work for the timing to work out, they both must recieve instructions to do this from some central thing, the central processor. It's really no different than when your computer's CPU sends instructions and data to the GPU of your graphics card so that the graphics card can render an image without constantly interrupting the CPU during every single step and just send a finished product back there, or straight to the moniter, or however it's designed to work. The only differnece is there's two of those external GPUs instead of one.

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
