If only. They have a different shape shift and enter key. It's not impossible to type on different keyboards at home and at work without mixing it up too much, but it is annoying, and not just a software configuration. (Source: am Dutch, live in Germany, have different keyboards at home and at work because I don't want to throw one away when it still works fine even if it's a little annoying.)
Programmers tend to have better typing skills in general than other people. But speed wise, real[1] touch typists leave general programmers[2] in the dust. This should not be a surprise.
[1] Touch typists who are specialized for typing speed as first priority. This doesn't generally include programmers because they are specialized for programming and typing is really just a secondary skill in being able to use "a tool of trade".
[2] Someone will now suggest that they happen to have practiced for a week and can beat everyone they know. Well done. Now you're still not a specialized touch typist... A real touch typist just needs to practice more and will still likely beat you. Or it could be argued they type faster due to characters/week.
