Logitech G15 G19 and other models also have a special small monochrome 
screen on them. Useful for some people.

There is a Windows and Linux drivers for this screen.

I don't understand, why Ctrl is moved down on modern keyboards. I 
always switch Ctrl and Caps Lock, because I use Ctrl a lot and don't 
like my hand twisted. It's much better to have Ctrl on the same line 
as A, S, D, F ..., like on the keyboards, I used a lot in the past 
(Acorn BBC, Amiga, Wyse terminals). I'm currious, what users modern 
keyboards are friendly for, they're not programmer friendly for sure.

Typists of course!

Many more typists than there are programmers requiring Control key 
on the most used rows

Modern typists use eletronic word processors with many control-key 
shortcuts, don't they?

My guess is, a typist use Ctrl more than Caps Lock.

Like Ctrl-B for bold, where Caps Lock for all capital were used on 
non-electronic typewriters.

Modern typists use the mouse!

:D

I'm afraid, you're very much right about this.

The mouse if for playing first-person-shooters, nothing else. ;P

There is a Optimus keyboard by Artemiy Lebedew tema.ru design.ru 
where on every key there is a video screen. It costed $500 several 
years ago.

Every key displays a video stream.

Like that.
