Yes. Also, I'd like to point out that learning a new keyboard layout doesn't interfere with your previously learned QWERTY skills. If you have to use QWERTY after learning Dvorak, then use it! Have more faith in your brain.
You're right! 'Pwn' and 'LOL' are right at my fingertips, even with my right hand on the mouse! Why have I been wasting my time with the Dvorak layout?
