Switching back to QWERTY

This is something I have not yet attempted. I know people who can go back and forth between the two, but I haven't put in the time to relearn QWERTY so I can be bi-keyboard-layout-al. It's really embarrassing when I try to use a QWERTY keyboard these days -- I go about 40 or 45 wpm, a little hunt-and-peckish, and have to stare at the keys. I try not to do it.

But, I've heard it can be done ...so more power to you!
