Google removing Windows from its dev environment

According to the article that I just read, Google is phasing out any and all windows machines in its development environment. This is after the recent security issues that cropped from Chinese quarters. New joinees are given an option to either take a MAC OS machine or a linux box. Wow. Isnt that cool or what?

Employees wanting to stay on Windows required clearance from “quite senior levels”, one employee said. “Getting a new Windows machine now requires CIO approval,” said another employee.
