suggestion for an open letter to keyboard manufacturers

Here's my suggestion for an open letter to all keyboard 
manufacturers. I would be happy to see it reach as many keyboard 
manufacturers as possible but before "releasing" it, I need your 
feedback on the draft. Please share your criticisms and suggestions. 
Corrections in English are more than welcome as I am not a native 
speaker.

Here it is:


Open letter to keyboard manufacturers: suggestion for the adoption of 
a new standard in the design of conventional keyboards


Address to the manufacturers of conventional keyboards

Dear keyboard manufacturers,

I would like to suggest to you to implement a new standard in the 
design of conventional keyboards. I am suggesting a number of small, 
yet effective improvements in the design of keyboards. Let me comfort 
you that what I am suggesting is not a radical change from we are 
already used to type on. Actually some of the suggestions outlined 
below can be seen on the market, gaining in popularity, though quite 
slowly. 


Address to the manufacturers of alternative keyboards

Dear keyboard manufacturers,

Little improvements like those suggested below will not make the 
current keyboard design completely friendly to the human body. But 
unlike the paradigm-shifting keyboard designs, their benefits can be 
felt in a matter of minutes. 
Adoption of the proposed standard would not make people rush to the 
stores for even better, utterly ergonomic solutions. But it might 
bring forward the concept of ergonomic typing a step ahead; and that 
is something we are missing on the large scale. 


List of the suggested improvements:

a)	separated number pad, attachable to both the left and right 
ends of the keyboard
explanation: the number pad takes up space which limits the area of 
movement of the mouse. The latter makes up for more reaching and 
stretching of the hand.

b)	 USB ports on the keyboard + legacy mouse port
explanation: convenient for  plugging the pointing device; a standard 
on Macs since long ago

d)	scroll wheels for vertical and horizontal scrolling built in 
the keyboard

pointing device

as copy, cut, paste, change keyboard layout, etc

h)	keys with letters engraved on them, sold separately, to make 
touch-typing easier 
explanation: letters engraved on keys would supply tactile guidance 
in touch-typing
learning curve: 
models on the market with this feature: 

i)	straight vertical lines of keys
explanation: touch-typing is easier with straight lines
learning curve: medium to high for those already touch-typing
