I think giving computers to children is good only if the quality of education they receive is good. I saw many children using their government-given computers to play GTA san andreas and Counter Strike while they were in the middle of a class, and the teachers didn't do anything about it because the government forbids them to take reasonable disciplinary measures (A teacher wants a child to pay attention during a class? Good luck, there's not much he/she can do) and also the goverments forces the teachers to make everyone pass every exam because "it is stigmatizing" for the children to get a bad mark on a test.
What I comment sounds absurd, but I have no reason to lie about it.
So, even if I consider it can be benefical to give computers to students in some conditions, in Argentina it's not well implemented.
