A couple good examples: When you touch the screen, and drag, the mouse equiv. action is clicking the button and dragging. But with touch, in many cases you want the screen to scroll, whereas with the mouse you want to select / highlight text. Also, with touch you don't have a "hover" operation, so you have to make "click" (touch) initiate a "hover" type of action in some cases, but in other cases you want touch to actually be the same as a mouse click.
