Design Constraints

Most of our users live in places where access to information is restricted, and computers are prohibitively expensive. The technology industry rarely considers new solutions to address this market’s needs. Imagine designing a music player for someone who doesn’t know that a right-pointing triangle means Play, nor know what a ‘playlist’ is. Perhaps the only music-playing equipment that person has ever owned is a radio. Or nothing at all.
We aim to solve these challenges throughout Endless OS.
