This is why I liked the older Android devices (as opposed to the new ones). Having physical buttons and a trackball were significantly better than both capacitive buttons and optical trackpads. Trackballs are significantly better than optical trackpads from a use-perspective. They work in all orientation, have finer grains of control, don't require awkward flicks to work, and have a much easier learning curve. The industry really needs to stop trying to the trendy thing and focus on things that work.
