"How many PCs are actually in 3DCG and not in third world countries or used for surfing the net during coffee breaks ?"

Well Karl, StudioMAX is the most widely used pro 3D software, yet it doesn't run on MAC (neither Houdini, Softimage, Final Render, NEXT LIMIT Real Flow, Electric Image Universe, etc...). So this should answer your question...

By the way, I think it's cool that "third world countries" can also use computer !
