You can have a Dvorak keyboard layout on a Mac really easily - just change the language in the international options. But there are no significant speed gains to be made using Dvorak, according to comparative studies. I started learning it once, and didn't find it any faster than typing Qwerty. Steongraphy, however, would allow you to type with a lot fewer keystrokes, in theory. Plus the time it takes to hit two or three keys together is less than hitting them in sequence - like the difference between a scale and a chord. I don't even know if it's feasible to do this on a normal Qwerty keyboard, but it'd be fun to try. (Actually, Kevin Marks is curious enough to see if he can't hack something together...) As for whether it would be worth it... I am in enough situations where taking verbatim notes would be useful that I think it would. But maybe that's just me! ;-)
