I was introduced to Mathematica (version 2?) by a professor of mine when I was undergrad in Zimbabwe. It was on a NeXT machine (the only such machine I ever saw). I have been using Mathematica ever since then. I'm playing with it on the Raspberry Pi and i think its fantastic that such a tool could be available for so cheaply, especially for people in developing countries.
In the near future I would like to send a bunch of raspberry pies (sp?) back to Zimbabwe with Mathematica installed but I have one huge request. The Mathematica on the Pi does not have documentation included. Internet access in Zimbabwe is sporadic and expensive, so I would like students to have local access to the help system. Is Wolfram working on a way to make the documentation downloadable? I do not expect to have sd card space limitations.
