A friend of mine just sent me a link to a page for the ReactOS free Windows compatible operating system. There wasn't much information about it except that it was compatible with Windows (they didn't say which version) but they made it sound great. Since it's free and because over 100 people helped to develop it, I'm a little concerned about security and about how the developers are paying the bills (advertising, collecting user data, etc.?). Has anyone else heard of this OS or have any experience with it?
