I can't justify replacing three 23" monitors with new touch screens, and knowing MicroSoft, something will be buggy about the new version. I have been a lifetime user of MS and cursed every new OS they came out with. I use it because I have to and don't really have a better choice. Plus, I don't like the idea of having finger prints and smudges all over my screens. It's clever but not really necessary to the way I work now.
I agree, albeit, my Windows upgrading has always been pretty painless; nothing too buggy to report, in my experience.
I think they want to make Windows work like a smart phone, which is a love/hate for me. Love Android, hate touch-screen typing (must have tactile keys!!!! :^)
So mouse and keyboard are going to be tough to get away from; and if I'm using them, I want the control there and not have to swipe / poke the monitor. But it's probably the future. So I'll have to adapt, I guess.
One irony is that I began 25 years ago on a dumb terminal attached to a Unix network. And we're heading back that way, with everything (soon all our apps, too) being remotely hosted with our phones/computers merely being dumb terminals on steroids. LOL
