Inspired by this post on Slashdot, I finally took the plunge and shuffled the keys around. Although my typing is a bit slow at the moment, I can see some benefits from the Dvorak layout. Like NZSL, all the vowels are sensibly lumped together. Already the keys are playing a measured rhythm, alternating much more evenly than the lopsided QWERTY. My brain is having a field day as I'm writing. It's still like playing Scrabble and Memory at the same time!
