A few years ago I wrote a book about developing big complex networked apps. It had "Enterprise" in the title, based on the idea that mobile device OSs would become dominant - which they did - and that the evolution of tablet devices would continue to where powerful devices like the iPad Pro would overtake the use of Mac and Windows laptops - which they didn't. Windows and MacOS are full of compromises but are usable. Chrome OS is a contender for users that need a simpler system. What addressable segment is left? You pretty much have to make the case for replacing Windows. But you can only hope to replace the "voluntary" Windows seats. Many Windows users have no choice.
