If you don't race but ride in a group, every time you rotate off the front and accelerate to match the speed of the group when you reattach to the back, wheel weight matters.
Agree you your and BD's assessment of the relative importance of light wheels. I go on road rides and more or less maintain a constant speed. Therefore, I really don't obtain much of a benefit from a light wheel due to it's weight. I get lots of benefit from few spokes in crosswinds and nice tires are better for anyone at any time. If I raced in a stop and go environment, then I'd want light wheels for the improved control and agility that they offer. On the road, aero trumps weight, though both seem beneficial.
