Yes I agree flecc. Trouble is, if I'm doing something mundane like data entry i.e. transcribing, I just want to do it as quickly as possible!
However, if I can type faster, for longer, and more accurately with DVORAK, thats great!
Its a bit like riding a more efficient bike I guess: its can transform the typing experience from hard work and repetitive strain (cf squishy, energy-sapping suspension!) to an enjoyable exercise
