No - makes no sense on desktops or laptops
I just can't see the logic or productivity to a touchscreen on other than a tablet. I'm perfectly content to live out the rest of my life with a real keyboard and mouse. Maybe I could wake up one year (decade?) and have a light go off in my head, but it just seems like a solution looking for a problem to me. And whatever it solves (if anything) is not a problem I have. And maybe I'll look up in the sky and see flying pigs too. I'd say both are equally likely.
