The fact that Polish language has 2 keyboard layouts installed by default probably costed humanity millions of dollars in wasted time, helpdesk calls, etc.

You see - the "typist layout" (the one nobody uses) has "z" and "y" switched. And by default both layouts are enabled, and the shortcut to switch between them is Alt+Space (or Ctrl+Space - I think it changed at some point?). So when you have "z" or "y" in your password and you accidently pressed "alt+space" - your password "stops working". But you won't see why - because it's all stars. So you try 3 times and you have to call helpdesk.
