This project, as it seems firstly obvious, poses some ethicals and technicals questions. But, the more we dig these questions, the more problems we find. A lot have been, of course, strongly considered (the power supply, the screen, the networking capacity, and so on), but some aspects stay confusing. The aspect I want to focus on is merely how can millions of identical laptop be secured enough to avoid to be infected by viruses ? Just think that how it would be easy for a hacker if all the computers would have exactly the same architecture, the same softwares and, as a consequence, the same security holes. Here, the project OLPC offers the opportunity to spread viruses with a bewildering ease, as soon as a remote hole exists... which is not really absurd...

In conclusion, I see two observations. First, heterogeneity is good to fight against propagation of viruses. And finally, the relative difficulty for OLPC to be connected to internet, due to the bad network coverage of the development world countries, is maybe its better way to bother the propagation of viruses.
