Dvorak links to get you started.
Back in the old days people would type too fast and jam the hammers. Qwerty was designed to slow people down to prevent jamming.

I'll be getting mine in a few weeks, then I will have something of substance to say about them. With that in mind, I can't really answer your questions.
What say you, Lomas, about Dvoark keyboards?
Apologies, Eric Seavey. I didn't mean to hi-jack your thread.
