Well, according to Leliel's Java test, about 56 WPM after corrections for errors. But I probably type faster than that on average, since I've never been one to look at the screen while typing.

The interesting thing I've noticed is that my typing speed seems to increase dramatically right after I've finished with a session of hard-core piano practice -- especially if I've been practicing a quick-tempo song, like Mozart's Rondo Alla Turca. I also think my typing is more accurate after a piano-playing session. Any other monks notice this effect? (I'm definitely gonna keep a link to that Java applet for the next time I really get going on the piano... time for some empirical study.)

Another think: I'm a self-taught typist, just as I am a self-taught pianist; can't play music from a piano book (well), just as I can't type stuff straight out of a book (well) either. All I know is that formally-taught keyboardists (whether computer or musical) often wonder how I can do what I do with such lousy style. ;p
