I'm a touch typer, but not in the standard sense. I don't look up the keys while writing and use most of my ten fingers, but I don't use them like it's taught in touch typing. I know exactly where all the keys are and I intuitively press them with some fingers depending on which is nearest or easiest at the specific moment. According to [1] I can easily type faster than 600 keys per minute, more than all other people I know.
I don't think I should learn touch typing to further increase my typing speed. Right now most of the time my pondering over coding problems is limiting my typing speed, not my ability to move my fingers.
But maybe it's worth learning touch typing to reduce the stress on the fingers and be more egonomic?
Actually, from an ergonomics perspective, you would probably be worse off touch typing.
Traditional touch typing trains you to hold your hands in a consistent position over the keyboard. It's the act of holding your hand in the same position all day--whether that's over a keyboard or around a mouse--that leads to carpal tunnel syndrome.
(For the record: I touch type mostly the way I was taught to. My wrists do occasionally bother me. I'm 24. YMMV.)
