It has a TV out and an HDMI Port. I don't know any family without a TV (well very few, but they don't have a TV by choice and not because they can't afford one, however they have a computer and therefore a computer display). RasPi is a UK Company. The European community is regulating cellphone chargers. They must use an USB Micro-B connector (with 800-1000 mA output). Guess what? This is also the sort of power supply the RasPi needs. Since most Europeans get a new cellphone every 1-2 years, these chargers are disposable (every new phone comes with a new charger even though the old one is still working perfectly). So display available, check. Power supply available, check. Now all we need is an SD card, a Keyboard and a mouse (USB). A cheap keyboard and a cheap mouse would not cost more than 15 us dollars. And if I were a smart kid, I'd ask family and friends if I could buy used ones (which I probably would get donated). Nearly all families already have a mac or windows pc (but might not want their children to break it while experimenting) mouse and keyboard could be used from the already available computer. Well, now we have only one item left that is missing, the SD card. Many digital cameras are replaced here with smart phones. It's not the same but I see those aging cameras laying around in many house holds. Guess what, they often use SD cards. But since the SD card needs to be reformatted and somewhat inserted permanently into the device, it might be reasonable to buy a separate one. This leaves us with one extra expense: a new SD card for $20-30, big deal! I personally think the RasPi team has a very neat design there, don't you?
