good lord, what usabilty genius created that?
to begin with, everybody aroudnyou can read your pin and then, you stay  
there and tap the screen in the faint hope it might work somehow?

and, just out of curiosity, what do you do when you need to correct a  
typo? the screenshot shows not delete or backspace or so.
