Unix as an element of literacy

Linux Today has this interesting piece by Prof Martin Vermeer (Finland) who argues that Unix is an essential part of computing literacy: Windows is made for the illiterate who need to know very little before using it. Unix on the other hand is designed to allow literate users to do anything they want. Therefore, Unix should be taught in every high school to ensure some level of computer literacy. I've heard similar points of view from canadian and french academics... I hope they are heard.
