I learned to type with speed by playing Police Quest when quite young, and developed a quite quick, but interesting style where I never use my thumbs. I tend to cover roughly 2/3 of the keyboard (the left side) using my left hand, and the remaining 1/3 (and 10-key) with the right. It's worked out well for me, and I can touch type both code and English wonderfully. The only time it falls apart is when I find myself in front of a split, so-called ergonomic keyboard, which expects each hand to do a 50% split.
