Why only for poor children in "other" countries?

You're looking at an image of the XO-2. The second generation of the "one laptop per child" project. You know, where the poorest children of other countries are supposed to be able to get an affordable laptop so that they can learn and keep up with the rest of the world. The new version is a dual screen, touch-screen laptop that will be touted as an e-book reader that can hold up to 500 e-books. But which will also be able to be used as a computer with a virtual keyboard. My question is, why does this have to be targeted as something for children of "other" countries. Why not the children of this country?

Something like this would have been fantastic when my son was in school. He had to carry about 30 pounds of books back and forth to school every day. With something like this, at the beginning of each school year, he could have just downloaded all the books he needed for that year, and had one small, lightweight thing to carry from class to class. He could have taken notes on it, accessed encyclopedias...etc. Everyone knows that the public school systems in this country suck. Think about how much money, resources and time something like this could save our country if all our school-age children had access to something like this!
