I can't believe I lasted this long with the control key in the wrong place but every time I spend just 1-2 hrs on a machine with the control key properly located next to the A, my left pinky is at ease again and it complains when I return to the windows layout.

So, finally, I installed a little utility called ctrl2cap I downloaded a while ago and I now have three control keys! I've lost my caps lock key, but I don't really care about that.
