Ack, I stopped reading at "most people in the developing world have no access to computers". If you aren't aware of the degree of penetration of smartphones in the third world you've been living under a rock.
Can you point me to your information? Even with smart phone adoption, currently the worlds internet penetration sits at just 34.3%... There are only ~1.10 Billion smart phones in the world vs 7.1 Billion people alive... See the first link below, even the predicted future penetration for African, Middle East, South/Central Americas and Asian Pacific countries sits below 50%.
