So the moral of my story is you can give 1000 people a computer and even if only 4 people start doing great stuff with it, its better than no people. They did spend EUR 200 for each computer, so if it only helped 4 out of 1000 kids, then you're spending a _lot_ of money on them. Even more importantly, the research shows that overall, the kids performed worse on the measures that the researchers found important. So for those four kids that do start to perform better there would other kids that performed worse. (unless you measure success along different variables that weren't taken into account in this study, but then we can't really conclude anything until a new research is done)
