Funny, I thought this was old news. Pixar had been talking about doing a switch for a long time, and I know that they were working on a Linux port of their software (Pixar is a software company as much as a movie production company).
Suns servers are expensive to maintain and just dont offer the bang-for-the-buck that they used to. Render farms are just a ton of CPUs that do nothing else but the final rendering of what someone had done on a workstation. They are basically closet monsters with no other use. Suns servers are a waste in that role (plus Sun and Jobs have something of a trying history).
The move is also not surprising in light of the fact that Pixar needs to prove to its clients that Renderman for Linux is actually a product worth buying. There is no better way to get that point across than to use your on product to make an award winning motion picture. Also, considering that Pixar is splitting from Disney, it is going to need to make sure that the profit margins are as high as possible (in case they need to front their own cash on future products).
