Linux in the mainstream

Some people say that Linux isn't in the mainstream. That it isn't known to a great many people. I tend to disagree. Of course, it's not as widespread as Windows. Everyone agrees with that. But more and more libraries for example are offering free Ubuntu CDs, spreading the love through means of education. And the popularity of the eePC and other mini-laptops have helped as well to spread the concept of a light-weight linux distro as an alternative to Windows. In fact, I have met quite a few people recently who have been asking about Linux as they hear it is "the best OS".
