I think there is pretty interesting potential for 3D design to be much superior in a stereoscopic interface than the flattened version of it you get on a 2D screen. Consuming anything 3 dimensional has the same potential benefits. Basically, you’re dismissing the third dimension with a wave of your hand. I’d keep that question open until we see more what application there are. People did say that the Mac was NOT an easier way of doing paper things and that they already had good ways of doing all office tasks. Look at how far the Mac has come from its genesis though. And it’s only true feature, at the bottom of it all, was using a mouse visually instead of keyboard commands. An interface style that was more intuitive and made things discoverable. Virtual computing can easily be as big a jump as that.
