I think we need a definition of what's a PC. A lot of people use a laptop as their main machine but it seems this is about fixed machines. Even then, I have a closet server and used to have a machine hooked to the TV. are these PCs too? For a machine in the living room, I'd love kinect like voice recognition 100times over a keyboard(google or youtube shouldn't need more). On a tablet or laptop, apart from programming or serious work, I'd prefer handwriting recognition if it was acurate enough, and I'm sure a lot of people who don't type daily on a keyboard would too.If mobile devices continue to grow, 20 years to get something usable on the desktop seems realistic to me. I guess keyboards will still be around, but for most daily uses I expect other input forms to be privileged. So ubiquitous, no.
