What is needed for the developing world is a new kind of computer. Something durable, able to stand long journeys over poor or even non-existent road systems. A computer that can get a working supply of electricity without needing a stable power infrastructure. A system that can offer networking, web access and all the trappings of a modern western workstation using only free software. Most importantly it has to be a system that can be built from scratch for as little money as possible, with the magic number being touted as only $100 US, meaning that countries can afford to buy them.
If you haven’t heard about the OLPC yet, check it out. It’s amazing just how feature packed the laptop is for a projected $100. They also list direct competitors, but the laptop still looks the best.
