125 WPM, using the ergonomic keyboard in my office. I'm still not entirely comfortable with it (I'm rarely in my office, so I usually just type on my laptop keyboard), and it feels like I'm going slower than what I'm used to. I think that I type faster on my new MacBook keyboard, but I haven't measured it.
When I was a kid, my parents owned a business. One summer, my mother decided that I would learn how to type because a girl needs to know how to type. So she sat 10-year-old me down in front of her IBM Selectric, draped a towel over my hands, and ensured that I learned how to touchtype. By the end of that summer, I'd hit 80 WPM. College is when I really started going fast, mostly because I started chatting online. IRC and MUDs did wonders for my typing speed, but maybe not my grades.
