Just an observation...
when my kids were young, I spent COUNTLESS hours pleading, begging, threatening,
literally whatever I could, to try and keep them from touching the screen on my monitors!
Didn't matter which computer it was...the old Amstrad PC, the IBM PS2, my home built
386 right up to present day..."Please, kids! Don't touch the screen!!!"...never worked,
I could always find little smudges all over the monitors. So, to say that users forego
"touch screen for the mouse"...nah, not without a lot of training!
