Hokusai, it is not strange that you didn't find any of the professional graphic designers who use Linux, because there is no good software for desktop publishing yet. Personally I convinced two people to buy a Mac instead of windows. I know some pople that would like to work on linux but Adobe Photoshop and After Effects is a problem. We are just forced to use Windows. OSX is good but expensive and when you want to build your custom hardware and you need a very powerful specs you are left alone. Poor reality. And for people who say that linux is difficult: If you are clever enough to learn the software, I hope you will learn linux as well.
