I've been touch-typing since high school. It was mandatory for us to take a typing class, but by that point I was faster than the class needed us to be, though my accuracy needed some work. The class was pretty much a joke for me. I'd type the test assignments two or even three times before the teacher called "time".
I've always been a computer nerd, and I used to type up stories in my spare time, so that helped me learn to touch-type. That skill has been in use since then, between IMing, email, programming and other things for both work and pleasure.
My BF, Awayfarer, can touch-type, he just doesn't think he can. I watch him type, and he goes about as fast as I can, but he stares at the keyboard. There's no way he can type that fast unless he knows where the keys are, but he has to look anyway. Whenever I tell him to look up he only does it for about ten minutes, then is back to gawking at it again. One of these days I'm going to get one of those covers that hides the letters and will glue it to his keyboard.
Oh, and that typing test somebody posted above says I type 79 WPM net (I'm assuming that takes into account errors). I could probably get faster if I took it a few more times, but I don't really care that much.
Heh, I just looked down and realized that I really don't have a choice anymore to be a touch-typist. I've worn all the letters off of this keyboard. Ooh, and actually poked a hole in the T key. No kidding, there's a hole there.
