I use a Toughbook with touchscreen and find it much more intuitive for quick selections. However, most software doesn't lend itself to using a touchscreen.
Unless you have a stupid large screen, change the resolution to a very low level, or have finger tips that look like pencils, using a touchscreen with most programmes is a PITA.
Having said that, I use mine in the car with topographic mapping software, and it is a lot easier to use a touchscreen than use the keyboard shortcuts.
