I may be old-fashioned, but what children need are not laptops and other fancy educational aids. What they need are colorful, attention catching books, airy well-lit classrooms, hygienic food, clean toilet facilities and above all highly motivated teachers. Provide these basics of education and you will see illiteracy vanish from the face of India within a generation. You cannot expect children who do'nt know where the next morsel of food is coming from to stay focussed on their laptops.
