I like this quote from Hacktivate:
We need to stop underestimating people. Don’t expect Africans to be content with boring old SMS and voice for long. Smartphones, droids and even iphones are much higher up Maslow’s hierarchy of needs than we realize, especially if nobody around owns a computers, your schools suck, and the government controls the radio and newspaper. Africans have leapfrogged over landlines. They are now leaping over laptops.
(Desperate housewives, lonely on their isolated farms, also surprised the world by being the early adopters of the strange world of cranks and dials and operators that made up the original telephones of the 19th century)
