Am I the only one who thinks this whole OLPC idea, whilst noble, is quite misguided? Children in developing countries don't need $200 laptops, which after all are luxury items, they need schools, teachers, and textbooks. 

You can buy a lot of textbooks for a hundred quid.

Might be quite good for western kids though, although apparently you can't buy them??

but to subvert AMD

We already have OLPC widespread in the US -- practically every high school kid ends up shelling out about $85 for a Ti-83 calculator. 
This isn't just a calculator, it's a Z80 based computer that is used to run all sorts of applications including data collection devices. 
It's showing its age, though (surprise!) so replacing it with a more modern design could be a huge business, especially as experiments with trying to run education programs with classic laptops has been a dismal failure so far.
