I haven't used a touchscreen in a few years so they may have improved, but the ones we used to use in the systems we developed were horrible; fingerprints and grease and God knows what smeared over them after a few weeks of use for demonstrations and testing.
There weren't many other options for devices with the tiny screens we were developing for, but I can't see why people would want them on a general-purpose device that's large enough to have proper dedicated control buttons or a keyboard; I'm sure there are specialised applications where large touchscreens actually do make sense, but not to replace a desktop or laptop screen.
