old lightpens
Way back in the olden days, we had a mainframe with dumb terminals and these tethered light pens that we used to select fields and items with.
Our arms got really tired and we had lots of neck and shoulder pain with our arms up like that, so we eventually had to figure out as many keyboard shortcuts as possible.
I'm sure the touchscreen monitors will be much easier to use as you had to really press that lightpen into the monitor to get it to register, but I still see that it would take some getting used to.
Of course, when we first started using the mouse, I thought it was the most horrible thing and that I'd never get used to that either.
