They can be very beneficial at times - on the edge of a busy road with no shoulder, in a race or a fast group ride, in the rain or cold, etc. It takes a few seconds on you're on your way.
Also most new bikes won't handle frame pumps. The choices then are ones that fit behind bottle cages, or ones that hang out of pockets or bags.
