Key factor here is ergonomics of computer's interfaces that humans use. The size of the computer itself is much less relevant. It can be a desktop, a mobile computer, a super portable tiny computer. But the human interface is more or less of a constant, given that we, humans, tend to have certain physical parameters which aren't changing despite any technology advancing.
That's why computers with keyboards and wide screens aren't going anywhere, until other real alternative human interfaces will be developed. Touchscreens are good for what they do, but they are no substitute for keyboards, mouses and wide screens by any means.
Are you a writer creating your next magnum opus? Or student who rushes to finish some course work in time? Try doing it on the touchscreen. Are you creating some music or videos? You won't exchange your wide screen editor with tons of controls for any degraded touch screen experience. Are you a developer who uses IDE? Forget about touchcreen tablets - keyboards and monitors are your friends. Are you a hardcore gamer? You won't give up your keyboard and mouse and your high end GPU/CPU for any tablet for sure. And etc. and etc.
What I'm trying to say, is that tablets interfaces aren't replacing regular (i.e. classic PC) interfaces such as keyboards, mouses and wide screens. They are only complementing them. So all this talks about tablets killing PCs is nonsense.
Have you heard of iA Writer for the iPad? Many writers love it and favor it over a laptop keyboard. I also have hardcore-gamer friends who nowadays spend hours playing games on a touchscreen. I think you're being a little narrow-minded in thinking that a physical keyboard and a pointer device you hold in your hand are the holy grail of human interfaces.
Yeah, try playing some latest RPGs like Witcher 2 and etc. on a touch screen. Comments are welcome ;)
Those who need fast typing won't exchange keyboard for a touch screen ever. I didn't say touch screen isn't useful. But it's not a satisfactory replacement for older technologies like keyboards. It's just a useful addition. Replacements will come later.
