I disagree that it functions in a logical way. I literally have to have an app to make my bluetooth mouse scroll in the opposite direction than the trackpad, because there is "Scroll Direction" checkbox in both mouse and trackpad... but it's actually one config option. And with every update I hope that they don't screw up that app... OSX has less and less of "less is more".
