Haha, maybe I'm just a bigot, but I thought that going for the 2-finger hunt-and-peck style to touch typing was just a natural evolution.
I recently switched to the 10-finger-system from some custom, maybe 6 finger system, as sitting a whole weekend switching between gaming and programming eventually made my left hand hurt like hell.
I typed 80 wpm before switch, and I'm almost at that speed again now. There's maybe a month since I switched.
