tracking wildlife with a pda

I just read this article on the Bright website about bushmen using digital devices for tracking wildlife in the Kalahari.
After reading the original article I was astonished.

Here we are, complaining about how to get teachers to use internet tools, mobile devices, streaming video, etcetera. Because the teachers can’t. It’s too difficult for them. We can’t expect teachers to spend time learning how to use rich media. How we try and make everything easy and ready to use for them!

And on the other side of the world, people who can’t read or write are using a mobile device! And for a noble cause too: ecotourism and environmental education. The solution is this: if there really is a need, we can make the software that is easy to use so nobody can ever say again that something is difficult, or impossible or time-consuming.
