If its that much better, but no one uses it, who the hell cares. You can espouse all the features you want, but if testing shows that it doesn't really matter to anyone, meh.
What is your definition of anyone? I am teaching Dvorak to some really young students, whose habits are not malformed with Qwerty. They are extremely thankful to me, no one is willing to return to Qwerty, time to gain a touchtyping skill is 10 hours from zero to hero. So, my "anyone" reports that Qwerty does not matter to him. Probably your observation is based on the fact that an old dog can not learn a new trick.
