It brings up some interesting points:

I wouldn’t say that they were ‘hidden’ dangers though. maybe some just not completely obvious.

What is obvious is that with a reach of around 60cms, my dual screens are 20cms out of reach. They have to be back as far as they are to save me having to put stress on my neck as I glance from one to the other. I set text at 120% to save eyestrain. If they were touch screens, I would have to push in the keyboard tray and slide the chair forward. Why would I want to do that when I have two perfectly capable input devices nicely placed , bridging the gap?

I will not be paying out for touch screens unless my standard LCDs break and nothing else is available, and for the reasons above, I will not be using the touch facility anyway.

While I was messing with the laptop and a variety of lap desks and cooling bases, I noticed that when the machine was on my lap, the weight of the lid had a tendency to start a turning motion, the pivot point being the hinges. With both hands on the wrist rest, you would never notice anything untoward. Even if a hand is removed to use a mouse, the mouse adds no extra pressure to the screen hinges. Touching the screen changes the game, and one hand has to hold down the base.

I know one or two people who have touch screen machines, laptop and integrated desktop, but they are not used as touch screens. I don’t think that they know what to do with them, how to set them up, or ostensibly have any interest in the function.

Phones, tablets  and e-readers are different. They have to be used up close and personal, in front of the area where a keyboard and mouse would be. One is left with no choice but to swipe, wipe and tap.

In the end, users will adopt an input method which works best for the machine in use.  Touch will be a part..
