The PDA Health Revolution

This is interesting not just in the way that it’s being applied or the fact that it is helping to revolutionize healthcare in the third-world (it is), but also that it is reinforcing the concept that some technologies require a much lower barrier to entry than others. Cellular technology requires towers, but not anywhere near the infrastructure involved in land-lines. As a result, many of these countries depend almost exclusively upon the wireless communications medium rather than the land-line infrastructure that you find throughout most of the first-world. This allows these countries to quickly shrink the technology delta between the first and third-world, and hopefully shrink the economic gap as well.
