Demonstrate it with a distribution. It does not have to have all the bells and whistles applications since the aim is to demonstrate a tidier more functional approach.
Shift-opening applications is a very deliberate action whereas the hidden files in /home/<user> are not really hidden are they? The are visible depending on which application you use, for example KFTPGrabber and Krusader. With these apps you are free to browse....and affect these hidden files....and thus have an accident even though the original intent had nothing to do with folder in question. This is why I am 100% convinced this is an accident waiting to happen (i.e. a very non computer literate user weened of Windows). Just because something is standard does not mean it can't be improved upon.
