A huge problem with touch UIs is the lack of mouse-hover discoverability. At least with desktop applications that don't have labels on UI elements, usually a hover will raise a tooltip description.
Touchscreens are just incredibly restricted control interfaces in general
They're trying to replace physical buttons with actions like swipes and in my experience swipes, pinches, double taps, all that stuff only works some of the time
A right click on a physical mouse works every time
