How will 3D help make my email, web browser, word processor or program X more efficient or better?
I don’t know. But the authors of email programs, web browsers, word processors and program X will know once they get the technology in their hands and start playing around with it. I can think of some examples in which the advantage is clear, the most simple of which is the Rubik’s cube. However, I cannot come up on the fly with a clear way to make any old program a 3D killer app. Much like the transition from command lines to 2D graphical interfaces in the 1980s, nobody will know until the programs actually get created and people start trying them out. Their innovative advances will most likely be so obvious and simple that we will all wonder why we didn’t see it before and how we all got along without it.
