Go ahead and laugh. Currently I am in my third corporate environment. In all three institutions Windows was/is the default OS. So I had to learn to survive. Maybe I should have also learned Mac OS or Linux, but since they were not required, I never felt the need to. Let's face it, we all have different areas of interest. You know your computer, I know my 6-7 languages (I use N810 to read RSS feeds from 5 countries, European and Asian, every day). unlike you, I don't expect people to have the same kinds of skills.
