I have fine motor control that is, at least, not worse than average. I nonetheless have to turn off all the fancy "3d click" stuff on Mac trackpads, or else my click-drag-drop operations go from ~100% success to more like 40% success. Took me a while to figure out WTF was wrong, the first time I got a Mac with that "feature". So please, no, no-one rely on this when writing software.
