What do keyboards have to do with typing system? The keyboard really just tells the system which keys have been pressed, interpreting that as QWERTY or Colemak or Dvorak input (or even stenographic cords) is entirely up to the computer receiving that data.
If you are trusted enough to make minor personalization changes to computers (installing Colemak or Dvorak), then it's maybe 1-2 minutes to get typing at full speed at any arbitrary computer. If you aren't, then you should spend the effort to get a better job instead.

Strictly speaking, not so (anymore?). Among other things, my USB mouse can transmit keystrokes. However, the computer can still respond in any manner to any input, including treating one letter as another. I think that macros executed in hardware could be royally borked by such a substitution, however.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
