I work for an NGO that has IT programs in Rwanda. I would love to see some package similar to this that would somehow integrate a screen with Pi. I just love Pi as a concept and I really want to include it in our programs.
As it stands now, we're in the same boat as you. Second hand laptops / netbooks are a far cheaper and simpler solution for us than getting PIs and figuring out what to do with screens, keyboards, etc...
You (and parent commenter, and others) should get together and have a website for "This is the stuff we need, and why we need it".
You'd have a suggestion of a package of RPi, keyboard, screen, etc. You'd give suggestions for what would be good, and what to avoid. You give a total cost, and the amount you can provide to that. You then ask people to donate.
You maybe put the faces of children on your request.
