Green power of the XO
Nice cuts from of the XO: 1) reduced chemicals in the battery; 2) low power needs of the machine (1/30 of most devices); 3) quick clip about the non-reflective screen (one slide below):

It was a very quick moment, but the basic rap was “you have to design this without fundamentally changing the production process or altering the materials. The answer for the non-reflective surface (important for some classrooms, but also for the book reader part of the XO), was to add onto the top of the existing low-power display.
