Wow, I honestly didn't know how widespread non-QWERTY keyboards are in Europe. Wikipedia has a nice map.

I live in Poland and we pretty much exclusively have QWERTY. QWERTZ is a historal artifact. Not sure if that's still the case but at least until recently, it was installed by default on Windows as an alternative layout, seemingly mostly to confuse non-technical people when they accidentally press the Ctrl+Shift combination to swap.
