Syllable is a volunteer project that is developing a family of easy to use computer operating systems. An operating system is the basic software that makes a computer do things. Every computer, and basically every electronic device that is a computer nowadays, needs one. The application programs that you use to get things done need an operating system, so they don't each have to reinvent the wheel.
Beyond knowing that your computer needs an operating system, like you need air to breathe, why should you care? We think that ideally, you shouldn't. Computers are now part of modern day life. You use them for all sorts of things you want to do. Application programs provide the functionality you need. Operating systems should provide the services that applications need to make the machine do their thing, but should otherwise get out of the way as much as possible. Many computer devices have almost become invisible, in your microwave and coffee machine for example, and so should operating systems.
And here lies the rub. Coffee machines and other special-purpose devices usually succeed in doing what you want, but many people can't escape the feeling that their personal computers are often working against them. Yet they are based on the same technology as the little computers that are helpful all during the day. Personal computers are far more powerful machines, so they should also be far more helpful, shouldn't they? Well, sometimes they are, but often they are not.
