I vote for 4 - to have keyboard for all users, who want QWERTZ layout. Not all are German, bul lot of us are guys from IT. And everybody form IT know what CRTL, ALT, ESC... is but only few of us have strg, eing on keyboards. It doesnt mather if its uppercase or lowercase. I hope, that F(x)tec is going to build international product and we all can accept some non-local (but internationaly understad) keys.
