I was going to say tactile positioning, but you seem to be rolling that in to feedback/layout. I would also add the distinction between putting your finger on a control and actually activating it. Capacitive technology doesn't provide a good way to handle that[0]. For an extreme example of the type of control you'd like to make such a distinction, consider the trigger of a gun. It may be important to be very ready to activate the control, and even more important to not activate it prematurely.
