Depends what you do with it obviously. Lighting software like Chamsys or Grand MA screams for touchscreen. For work I also need a Mac, and I hit the screen all the time. If you’re not into graphics / art design enough to have a separate wacom tablet, again it is useful. There’s no “it’s good!” no “it’s bad!”, it is just a matter of how useful it is for you. I don’t know on windows, but with Gnome touchscreens work very well.
