Typing was the most useful class I ever took in high school. I don't look, I use the home row, and I feel I'm pretty fast if I need to be.
Funny thing is, if you asked me to draw out a picture of a keyboard with all the letters in the correct spot, I couldn't. But for some reason my 'hands' seem to know exactly which key to go to in order to spell out what I'm thinking. It's odd.
