The Problem:
This book addresses the issues raised by people who are frustrated by the user experience with their laptop and desktop computers running recent versions of the Windows operating system. It seems as though the applications have not improved much in the way of features, while there is more pressure to register and buy subscriptions. Also, the software is largely proprietary and closed source, with tight restrictions on how it is used.

Frustration comes from computer users not having broad choices and being squeezed by corporate efforts to maximize value for shareholders. You've seen this before. It is literally the same kind of problem behind "shrinkflation" in food products or poor service quality in the airlines.
The Solution:
The solution offered is to migrate to GNU/Linux (or just, "Linux"), the operating system with advanced features, a vast array of fully featured applications, while also free and open-sourced. Free as in both "freedom" and "no cost". To be open-sourced means the underlying code of the system and its applications are available for examination, may be modified, and may be shared with others.

The bottom Line:
Move to Linux. It just works and does not nag the user. Here is a guide, succinct and to the point.

Linux applies the Unix Philosophy and smart operating practices to build an operating system using most of the internet, the world's top supercomputers, and several top notch desktop and workstation environments which serve companies, schools, gamers, and regular people who just want to get things done.

The book also includes a list of Linux distributions which are on the leading edge of a trend called "immutable" and "declarative" systems. These are exceptionally reliable, resistant to trouble from upgrades, and very easy to duplicate across any number of other computers.

Linux just works; it can do just about anything a user needs.
