Exactly. Windows has been consistently less than 70% of visitors on all my websites for the last 10 years, dropping to about 50% in one year. It has picked up a bit recently. So am I lead to believe that the vast majority of non-windows users run Microsoft office, when its still not available for Linux, and wasn't available for many year on Apples OSes. What other MS software could fill the remainder? It doesn't make sense.
