> Regarding sanitation, not sure if they are any worse than, say, door handles.
It will depend on the material of the door handles. In my experience, many of the handles are some kind of metal, and bacteria has a harder time surviving on metal surfaces. Compare that to a screen that requires some pretty hard presses in order to get registered inputs from it, and I think you'd find a considerably higher amount of bacteria sitting there.
Additionally, I try to use to my sleeve in order to open door handles whenever possible.
