It depends on what kind of machine you are using. If you are using a desktop then yes a touch screen is not a very ergonomic way to use your computer but then the mouse is not going anywhere.

But when a laptop or a tablet is being used, a touch is very natural because the screen is at the right distance and more importantly at a "right" angle. In fact it is way more convenient to use a touch based laptop instead of a tablet because of the angle the screen is at and the arm rest that the keyboard provides. Try it out yourself.
