No, I'm not going all "New Age" on you, this time I'm looking at how computers are going to get a 3rd dimension and how this will change the way we interact with them. The previous parts of this series have been based on extrapolations or previous history. This time I'm looking further forward, when technologies currently in long term development become available and open up a whole new realm of possibilities.

Wrong. The visual cortex is small in comparison to the rest of the brain.
There are at least 27 distinct regions of the brain dedicated to vision, accounting for almost a third of the brain's total mass. See the blurb for this Oxford Press book: http://www.oup.co.uk/isbn/0-19-852479-X or this University of Rochester press release: http://www.rochester.edu/news/show.php?id=1191 or this article from the International Biometrics Group: http://www.biometricgroup.com/in_the_news/03.07.03.html
actually, vision does indeed take up a lot of the brains processing power, the visual cortex is devoted to one sense, which is vision. there is no other part of the brain dedicated to just one function.
How about the hippocampus, which regulates the storage and recall of memory (much like a cache)? Or the medulla oblongata, the body's autonomic control center? There are many parts of the brain which are specialized to perform a single task, although you could certainly quibble about their scope.
