I would say that even a tutorial mode doesn&#x27;t get back all the usability, because you need to explicitly look for the tutorial.  In a desktop GUI, you have buttons, and they are obviously buttons.  You can figure out what they do by clicking on them.  You can usually find the keyboard shortcut by hovering over the button.<p>Even with a tutorial, there is no smooth transition in a touch interface.  Nothing to indicate that a double tap or a three-finger swipe will be recognized.  Instead of being presented with new features, the user needs to go looking for them.
