My problem with all the save Africa hardware/software projects, is they seem to be made by people who don't live in Africa. I'm not confident they even have a grip on what the customers actually want or need.
On the technical side they "only" have a wikipedia dump for the moment, but on the project side they have had some success in deploying it, so maybe you can have a look at what they do (warning: Afripédia is made by and for french-speaking people, you may have to learn it :)

Do you think people in South Africa need this thing to read about Ebola in 2014? How ignorant are you really?
Signed up 3 hours ago. Surprise.
But if you really think this project is a 'useless gimmick' then there's not much more to talk about.
