I wouldn't argue with any of that. Especially since my signature even with pen and paper looks increasingly psychotic. I only note that for me the change from mouse to tablet to Cintiq has been increasing happiness, but also that each needed changes in technique. In drawing/painting that's not a bad thing, getting a kick in the pants to try new ways of doing things. For sculpting I'm finding short little strokes with a stylus to wrestle a curve into place works best for me.
