I understood from my own experience that people at the very "bottom of the pyramid" do not require complex applications to get out of the extreme poverty. They need very easy-to-use and familiar tools that do not require them to spend more of their Adenosine Triphosphate while thinking. They are hungry. That is why in Sub Saharan Africa for example, many computer users use the word "plug and play" referring to a software or hardware that is easy to use. The wizard. Developing countries need a "plug and play" system. Whether a software, hardware, book or training manuals, all this must be very easy to understand. Computers do not often offer that, mobile phones does. Still, mobile phone is not a better learning tool than computer.

My point is this, while implementing ICT and Education policies in developing countries, policy makers should know that not any policy can be used at any level of poverty. Many people, including myself, have started using computer at age 20. Some in my village in the North-Kivu, DR Congo, never even saw a computer before, but have mobile phones in their hands every day. It requires a huge effort and sacrifice to catch up with many other people of your age in other parts of the world. On top of that, when you are 20, you have other important problems you need to solve in that particular moment of your life in order to survive: find money to finance your school, have clothes, a 1-bed studio, a girlfriend and you have to move in a big city to find more opportunities. All people of the above profile need is a machine easy-to-use that can help them learning while thinking how to solve other problems. it is only after you pass this stage of struggling to catch up that you will be able to think of other application, some of them can be complex.

Computers are more capable than mobile phones for many reasons as Dr. Kozma cited above. This is true when applied to a population that already has a basic or broad knowledge in mathematics and sciences, know how to use econometric analysis to analyze data or know the existence of websites. It is true for students or professors who are ready to solve real world problem. Not for people who are struggling to solve their everyday problem in their community in order to survive. Those are billions on earth.

For students and teachers, mobile phone applications are easy to use and do not require a complex training. Neither teachers nor students in Africa read the entire manual that come with a Nokia before they turn it on and start learning by them selves the usage. That is the power of mobile phone. For computer applications, governments and other local institutions need foreign aid in order to start learning how to build a basic website for schools with Joomla or SPIP. Then we have to think of corruption and bad governance after receiving the money for training.

While using the power of computer to solve complex problems in some part of the developing world, some other part of the same world might a "plug and Play" solution to solve very simple but vital problem in their communities. When we put all these solutions together, we might have a chance to prepare millions of people, from different layers of poverty, for a better life in the 21st century.
