I would like to put forward an idea to further the access to education. There exists a fantastic offline compilation named RACHEL from www.worldpossible.org. It is a large collection of good educational content. It includes Wikipedia for Schools, Khan Academy, Science videos, Healthcare and Medicine videos, CK-12 Textbooks, World Literature Ebooks and much more. If its possible, the idea is to deliver cheap mobiles preloaded with the 32 GB RACHEL compilation. For developing nations I think it could make a difference. It may be naive but I would be so happy if some version of this could be distributed with the cheap Firefox OS phone in a way that complies with the license.
Thinking about this further. For those who only have one smartphone it could be wise to have dual sd-card slots. With this you could then copy RACHEL easily from one card to another.
