ZDNet has an interview by Roland Piquepaille:
Inexpensive phones and pay-as-you go services are already spreading mobile phone technology to many parts of that world that never had a wired infrastructure. In terms of the people who had been left behind by previous technology revolutions, the mobile phone has already reached more people from more different walks of life than the PC or Internet did. As chips grow more powerful, even the least expensive phones will become cameras and Internet terminals.
The most important benefit of affordable PCs, phones, and bandwidth is encouraging the growth of literacies in the use of ICTs for the purposes of the poorest people in the world. The diffusion of the physical technologies is already being driven by the market.
