Ivan talks about various interesting things in OLPC including their own approach to power management that reduced suspend time from 15 seconds (regular computers) to ~233 milliseconds (at the moment of presentation), file system with object store and unusual security requirements.

He also describes “View Source” button on keyboard – probably the first Open Source promotional tool of the kind.

P.S. OLPC is running Give 1 Get 1 initiative that allows anyone to donate laptop to a child in development country and in return, get one for yourself. It just costs $400 for two laptops. Currently limited to US & Canada, but there are ways to get it elsewhere.
