Disclaimer: not an answer, but a follow-up question. I'm seeing lots of Colemak and Dvorak responses; has anyone switched to Workman layout and had a positive experience?
Yes, most certainly. I prefer it over dvorak too - much more comfortable and balanced (see my other answer in this thread). Add an ortholinear keyboard like a typematrix into the mix and it's the best typing experience I've managed so far.
