Operating systems - Linux III.

I have read an interesting blog article "Five crucial things the Linux community doesn’t understand about the average computer user" (Posted by Adrian Kingsley-Hughes on May 21st, 2007 @ 10:31 am).
I must agree with Adrian. And I want to add another reason - Linux community is community of enthusiasts, they are not mere users of computers. And average computer user wants to use computer as other equipment like car or coffee machine and no more.
