F numbers are great because they let us use the same exposure settings regardless of format, but that's only useful when you are taking a picture.

And that's something the equivalence-heads don't do much of?

I take quite a lot of pictures, but not while comparing specs to make a buying decision. I take my pictures with cameras that I've already purchased.

When comparing specs to make a buying decision they tell you nothing about the camera's performance and lead to people thinking that a compact with an f/1.8 lens will be better in low light than a full frame with an f/4 lens.

I strongly suspect that most people base their buying decisions on things like ergonomics or pose factor rather than seriously sitting down to work out that a 1/2.3" compact is equivalent to a FF with a pinhole.

A lot of people compare specs directly and think that a 20MP compact with f/1.8 has better resolution and is faster than a 16MP full frame with f/4. The misleading specs help a lot with the "pose factor".
