I tried moving to Dvorak in the late 1990s and I stumbled in the multiple language problem. In addition to me typing in English and Spanish, the fact that I do programming was the nail in the coffin to really being efficient in something else than qwerty. It also didn't help that I already was 95wpm in QWERTY.
If you alreay have a large repertoire of shortcuts it’s an extra pail to worry about when making the switch. I find that im using some shortcut that i can’t recite what they unless look down at the keyboard as they’ve embedded in the muscle memory.
