I know I'm swimming against the tide on this one, but I cannot see what benefit children derive from having the internet in school.
And, from what I've seen of my own children's education, computer classes are a complete waste of time. Learning how to type is about all that they learn. Classes in programming or other vocational uses (CAD, etc.) for 16-18 year-olds would probably not be a waste, but other than that, I can see no reason for having computers in school.
