I can type quite fast (easily 100 words / minute), but never had any official training. My hands are always positioned like your second drawing. Could it perhaps be that the standard way people are taught to type (i.e. fingers resting by default on the middle row with index fingers on the F and J key) makes people more inclined to bend their wrists which can lead to complaints?
