Do you use a Dvorak keyboard configuration?  If so, how did you learn?
pedalpete: I know I'll probably get downvoted for this but...I was looking into trying Dvorak a few years ago, and was talking to a friend that used it for a few years. 
He liked it, said it was a little bit faster for him than QWERTY.The reason he switched back is because with multiple devices, very few able to use Dvorak, the benefit of being used to using a single common standard (he felt) far out weighted any benefit he got from using Dvorak while on his PC.This is what turned me away from using Dvorak. 
Doesn't answer your question, but I thought it might be good to have another opinion here.
