The document discusses adapting Linux, specifically Ubuntu, for use on wide area networks (WANs). It outlines some key benefits of Linux like being open source, secure, and less hardware dependent compared to commonly used Windows OS. While Linux is good, Windows is more familiar and companies prefer spending on something with less user problems. The document argues that Ubuntu could simplify business environments by providing common business software like email, web browsing, office suites for free or low cost. Ubuntu also offers better security than Windows systems by using a user/root access model.
