Google's in the Stone Age?

I was having a read of this article by Andrew Orlowski. During the course of the article he mentioned:

By the by, you can begin to see Linux has such appeal to Asian manufacturers. It's not because it's particularly good - it's not. In computer science research it's Stone Age technology.

On the very next page he proceeds to say:

Sun too has complex, multithreaded machines in the pipelines, but only Sun, or maybe Google, has an OS that can bounce processes around the world.

Oops, what OS does Google run? -- Oh, it appears to be Linux!
