At least in the "early adopter" phase. But only by getting some out there
and playing with them do people find out what features are useful and which
aren't. You don't see manual spark advance and mixture controls on cars
anymore, but that was a standard feature in the early days.
And you're very right. New technology is rarely cost effective IF used to
perform the existing tasks with existing requirements. However, new
technology might enable new things (hopefully useful, but you can't
generally tell in advance) to be done that just cannot be done with the old
technology. Adaptive nulling and beamforming might be such an
application. Certainly, it's been useful in other communications applications.
