Okay, so the warping-sides demo is cool, if a bit funny to see using OS X as the starting point. This could easily be an optional KDE effect plugin that people with wide monitors would enjoy turning on, and find useful. I'm even chill with the idea that virtual desktops are a bit opaque for people outside the technorati.
I do find it a tell that the exact phrase he uses is "most consumers."
In a software context, I think part of the Star Trek utopia we should be striving for (and a sign we've achieved it) is putting a wooden stake through the heart of the word "consumer."
