content: Interesting points, but when you look at the computer history, the keyboard has always been an important part. The thing is, back in the 90's, you got eyestrain because of the CRT screens and RSI in your hands because of repetitive actions.  When the flat screens came and better keyboards and mouses came available the eyestrain got away so did the RSI. But nowadays with laptops and the tablets, my eye strain is back and I get more and more RSI. Companies don't provide a permanent place since you have a laptop, so you work where you find place and lighting condition are not always optimal. People work in trains and busses but again bad lightning, wrong position of your hands, and you even have to curve your spine. I don't like to type on a tablet because I lose the feeling of what I type and my hands are in the wrong position. With touch screens you also a great ability to press shortcuts.
