I'm not sure I accept D) as a full defense of a confusing system. I get that some things can't be made intuitive, and have to be learned. But "there's a video somewhere if you know to look" is a crappy justification for the current setup. As is, non-regional gestures compete with regional versions of the same motion and the enabled-by-default gestures aren't terribly well chosen. I've watched a lot of non-power-users work their touchpad, accidentally fire off either the wrong gesture or an unintended gesture, and then sort of click aimlessly until they get back to something recognizable. That's a sign that OS X is failing users, no matter how elegant things look to Apple.
