I disagree, sort of. I have a 5 yo and an 8 yo. If you let kids use a computer without guidance, they will learn how to use a computer from their friends at school. And what they learn is to fire up a browser (chrome if you've got it, otherwise Firefox) type "<some word> games" into Google and play thousands of really mind-numbing flash games. Go ahead. Try it.
