I mostly just game and browse the Internet and my daily driver is Linux. I have not come across anything that I needed Windows for so far, in a year and a half of not using Linux. There may be some games I was vaguely interested in that don’t run easily on Linux, but day to day tasks, 3d printing/slicing software, basic image editing software, browsers, coding IDEs, all work native on Linux.
Sure, if there is a specific software that you really want to use, maybe that specific software isn’t available on Linux. But one individual running into multiple things that only run on Windows sounds like it is a fairly specific use case. At best, someone might need to use an alternative program. At worst, maybe that person needs to keep a windows environment around. But that doesn’t seem like the case for the majority of people.
My reply was more about special use cases not being a good excuse that Linux isn’t ready. You’re right, most stuff people can easily do on a tablet or a phone, and that same stuff works just as well on a Linux machine. So someone that wants to do that stuff, but wants a machine more powerful than a tablet, can run Linux without issues.
