I would hold out to see how osx catches on. Many of the big 3d companies are creating osx versions of their software and afew studios are switching over. In fact SW Episide II has scenes that were render entirely on a macs with osx using maya. And I also saw an article in a 3d mag talking about how in hollywood Linux was the big thing, osx is linux based. It may take a while but macs could be the 3d platform of choice. After all the greatest 3d studio Pixar is owned by Mr. Jobs.
