I mentioned the 4 most common questions I get about the laptop, here they are, simply pulled from my recollection, I haven't tried to count all the questions I receive these days:

1) What gives you the right/why aren't you feeding the children/why are you imposing western material culture on the children?
2) How can that work (the price point/feature disconnect versus regular laptops)
3) How do I get one
4) Are you going to set up a business selling them to fund the project

Anyway, the slides from the talk are up now for those who want them. They are the same core content as the other slides, but targeted at an academic audience.
