I presume that you meant to say "You need to have a computer guru". Obviously for Windows you need to have an assistant to check not just your English grammar and spelling, but also to check that what you wrote was what you meant
Anyhow, the whole point of the rather overblown article was to emphasize that you do NOT need to be a computer guru to run Linux instead of Windows, and achieve pretty much everything you want to do.
Disclaimer: I switched to Ubuntu 11.04 about a year ago and have no intention of switching back, although I use Windows (virtualised) because my work is with MS SQL Server.
