This is a talk about OLPC at the Open Source Summit of the Mass Technology Leadership Council by Ivan Krstic and
Eben Eliason which includes details and demos of the software. Recorded by Dan Bricklin on June 19, 2007.
This video is more about the UI, some of the apps, and how this all relates to Open
Source. It includes demos of a running XO, too. For a general programmer
population (and maybe even a general techie population) this is a very good
and powerful introduction.
