I think being able to touch type for the sake of typing efficiently is only the beginning. In a sense, it's a mark of a heightened brain-computer interface. It's a freeing feeling when you don't have to use your sight for direct motor control error correction. This is why I'm such a fan of programs with extensively configurable hotkeys/macros, tiling window managers, and (when constrained to Windows) Autohotkey. Much more than typing wpm improves if you're familiar with your keyboard. It gives you a much tighter loop between your executing your intentions and affecting the computer. This can be used for seamlessly executing macros or hotkeys in programs, switching window focus with barely a thought in a tiling window manager. Force multipliers.
