The problem is once you know QWERTY you can't deprogram yourself to use any other system. Once you learn QWERTY your fingers are PERMANENTLY hard-wired.
A few years ago, I set my computer for Dvorak, posted a chart over my monitor, and was typing moderately decently (about 40WPM) in a couple hours and even better (about 50WPM) a few hours after that. If I could find a keymap which would put the uppercase, lowercase, and "Alt" letters in Dvorak format but keep the control characters in QWERTY (so the ZXCV group work for Windows stuff, and the ctrl-letters around the ESDX diamond (any idea what might use those?) work as they should, I might like to give it another go.
