I'm always behind in my reading, but I recently finished this article about the OLPC -- "Una Laptop por NiƱo" (free registration required) --
https://www.technologyreview.com/biztech/20572/.
Obviously, not directly related to libraries here in the U.S., but sure does give some good perspective!
I will be interested to see the second version of the OLPC and also products that may come as a result of Mary Lou Jepsen's efforts -- "Simplified Displays: Mary Lou Jepsen is developing technology originally created for the $100 laptop project" --
