Hm. I use all my fingers, but the pinkies only hit Enter, Shift, and other modifier keys. But I learned to play piano before I learned to type, so it has been remarked that I type like someone would play the piano. I employ a lot of hand movement, and employ a lot of "hand rolls".<p>Not only can I maintain about 90 wpm normally, but I also don't suffer any RSI type symptoms. I think the downfall of touch typing is actually that it reduces the motion of your hands, so you find yourself making a lot more painful reaches. In piano playing, unless you are playing a big chord you don't stretch your fingers, you just move your hands so that you don't have to.
