waiting is not a good ui gesture.
eg: volume control, it is much more intuitive to have something that moves, and preferably has a linear correspondence to the thing that is being controlled
so static buttons that have to be held in a position are not helpful.
it is much more intuitive and convenient to move something to change something else like volume. so a slider or a wheel would be a much better control than two static buttons that one has to keep holding until the desired volume level is reached.

Same thing goes for the long click for a context menu idiom.
