The billion-dollar-a-year movie, recording and advertising industries are all Mac-centric. It's preposterous to talk about user share when you're talking about the world--literally the world--of computer users. The majority of the Earth's PC machines are owned by hobbyists. I work in motion picture post-production and you'd be laughed off a sound stage if you asked where the PC's were. Initially, Windows machines were used in the offices for accounting and data processing, because no one wanted to waste a good Mac doing those tasks. Now PC's are beginning to disappear there as well.

Give Industrial Light And Magic (George Lucas' company) a call. Ask them what machines they use. Then call Disney, Pixar, Warner Bros., Universal etc. When you're done there, dial up Sony Records, Arista, Dreamworks (Geffen). This is not a niche market. These are hugely successful companies creating major product for the world. They don't give a rodents tushie about platform wars. They care about the best product that can be produced in both a cost effective and quality effective way. And they don't do Windows. Sorry, they simply don't.
