As an old time computer user (a window manager's only real use is to enable me to run multiple copies of xterm simultaneously :-) this emphasis on the keyboard is SENSIBLE.
My biggest bug-bears are (1) being expected to use the mouse, and (2) bloody autocomplete! If I want to type "10 Jan 2012" I don't want to end up with the system recognising the year and giving me "10 Jan 2012-07-28"!!!
Don't forget. The whole point of being a touch typist is YOU DO NOT LOOK AT THE TYPEWRITER (or screen). If the computer is trying to be halpful it's going to mess you up something chronic. How many of you can outperform a touch typist?
