It is hard to give a precise answer, because:
-I don't know how the sales exactly split between Windows and Mac (my licence covers both), but I have an idea from downloads.
-It is more work to develop cross platform.
-Cross platform development always results in some compromises.
But, on the whole, I am happy that I choose Windows + Mac, rather than just choosing one or the other.

Note that while there still is a market for desktop software, it is shrinking. Many Indie developers now sell web-based products (SaaS).
