I'd learned Dvorak using a Kinesis keyboard. I use both Dvorak with the Kinesis and QWERTY with a standard keyboard. The slight difference in profile is enough that I've never had interference, and use both comfortably. That said, it hasn't been an enormous speed increase; I'm roughly equally as quick with either.
