What's the importance of computers?

I have asked about this before but did not get any good link. I need to find an article that describes the importance of computers in our society. The article should be written after October 2000. I have searched Yahoo but if it find some articles related to computers, they are outdated. I don't know why people haven't written that kind of simple article that just describes why computers are used in our society.

If it's that simple why don't you write one yourself?

Because I need to find an article that somebody else wrote, and then I need to write about half page long summary of that article.

Sounds like fun. Can't say I envy you. Being in education that is.
