Basically title. Do you know of any companies that use desktop Linux?
I can think of two in my area in Brisbane - Adfinis and Red Hat. Both have a pretty small presence here from what I last heard (several employees each).
My employer allows the Linux team to use Linux but it's discouraged and our lives are made somewhat difficult.
Can't say what company, but a large company that provides education tools has been looking into ways to be less dependent on Microsoft. They have some of their employees currently using Linux computers right now. Some employees in the IT department still need a second Windows computer.
