This paper studies the distribution of computer use in a comparison between two of the most dominant suppliers of low-cost computers for education in developing countries (partly because they involve diametrically opposite ways of tackling the problem). The comparison is made in the context of an analytical framework which traces the changing characteristics of products as income rises over time. The crucial distinction turns out to be the way sharing is handled in the two cases. In the one no sharing is allowed while in the other sharing is the basis of the entire product design. Put somewhat differently, the one computer is intensive in a high-income characteristic whereas the other relies entirely on a low-income characteristic.
