Yep. Worse still, he's wrong even on that small point.
I'm working on Delay Tolerant Networking for mobile phones, mostly for deployment in isolated communities in the developed world. Mobile phones are everything OLPC strives to be, cheap, portable, power optimised, connected and hackable. Better still, they do all this now. They're already available in any country in the world, manufactured in extreme volume, we don't have to wait for some philanthropist's wet dream to bear fruit.
Any of the software I write could be trivially repurposed to suit the needs of the third world. Then people could get the benefit of access to modern information networks without necessarily having to have all the modern infrastructure in place first.
You could sum it up as "Notebook PC's are a good idea for the third world - better even that mobile phones". That's it - nothing more.
