Can you give some examples where it's more representative? Average height? Average income? There are a lot of arguments in favor of median as a more intuitive replacement (and it is frequently used thus) but consider that:
a) Some people have ZERO income.
b) Either an odd or even number of people have NEGATIVE income.
Every day I deal in execution times, rounded to the nearest integral number of milliseconds. Lots of zeros.
A measure that is (a) not actually intuitively correct, (b) very hard to calculate in your head, and (c) useless for many, many non-trivial cases is NOT a good replacement for "linear mean" which is (a) often intuitively correct, (b) pretty easy to calculate in your head, and (c) always works, seems better.
