The keyboard has the letters specially arranged so people don't suffer from RSI, and when they know how to use it, they generally have to move their fingers very little.
I thought, the keyboard has letters arranged to slow down typing on old mechanical typewriters to avoid proficient typists jamming the things when the arms collided if you typed too fast. Nothing to do with RSI (which hadn't been invented in those days
)

That's largely a myth (by the time QWERTY took its ~final form, started getting popular, there were no technical reasons... http://en.wikipedia.org/wiki/QWERTY#Contemporary_alternatives ), promulgated by the proponents of some alternatives (while http://en.wikipedia.org/wiki/Dvorak_Simplified_Keyboard#Controversy )
Plus, QWERTY/Z was used internationally in old mechanical typewriters, in many different languages - you'd think it would make a difference, jam easily in some languages; but it didn't do that.
Touchscreens have no purpose after a certain size. [...] after, say 10 inch displays, any movement is very difficult, time consuming and tiring.
That's like saying big drawings are awkward ...drafting tables are often quite large. Big touchscreen could be awesome for manipulating media, or as a proper evolution of the drafting table.

Touchscreens have no purpose after a certain size. For a phone or tablet, sure, they're supposed to be small, slim and lightweight.
But after, say 10 inch displays, any movement is very difficult, time consuming and tiring.
The mouse evolved over the years to a certain shape to fit your palm, and generally, you don't need to move more than a few centimetres to reach anywhere on the screen.

Buttons will always be here. Look at Sony, they had this dilemma with PSVita, and now it has a "touchscreen" which is actually a well placed touchpad.
