Its the creepy camera that is going to make this go mainstream eventually - not looking at others, but looking at your hands. Gesture recognition gives you a virtual keyboard and touchpad that is always at hands reach ... No need to disturb anyone else by babbling to yourself; no bulky tablet or rat tailed critter or mini-surf board. Just some quiet hands, easily hidden behind a desk in a classroom or other public place; the gestures will probably be quite difficult to read from other angles, too, so you will have privacy in your communications. ( What the hello are people thinking, talking loudly into their cell phones about their most private lives? NO, I don't want to know about last nights date and his mis-shaped ... )

The PC is dead, MS is building buggy whips for the horse and carriage. The share of PCs that Win 8 owns is irrelevant; the share of phones and tablets is the key, and Win 8 has virtually no takers. The future is Google Glass; with some improvement in the image projection, you will have a huge virtual screen, with voice recognition and camera based gesture recognition for the text entry and touchpad. For those are old school, a nice clicky bluetooth keyboard will do fine. Ah, and this is also the death knell for the HDTV; the resizable image will appear as if you had a 100" HDTV if you want. Don't think 2014; think 2016 or so on this one. Windows 10 is going to have piddly sales.
