I have one of those old indestructible IBM model M keyboards with removable keycaps. I love that keyboard. I decided I'd try to learn DVORAK and work with it regularly, so I did so. And I realized something: every time I'd work with a keyboard, I _will_ be working with QWERTY. There's no way I would request to an employer that I have a special keyboard just for me, or try to reconfigure software to support it.
So I went back to QWERTY. May not be ideal but I know everyone supports it.
