Not sure how accurate these figures are, but they make sense considering the environment -
I asked Adobe (just before they released CS3) why it supports Mac OS X. I received a response from Russell Brady, PR Director of Adobe. According to Mr. Brady, Adobe’s sales in its last financial year (2006) “were 77% Windows and 23% Mac. In some markets, such as the creative professional space, the Macintosh percentage is even higher. The Macintosh market is huge for Adobe and, by most estimates, we’re the largest supplier of Mac software on the planet.”
