Re: "Home users don't use Illustrator, Photoshop, Xcode or Autocad or one of those hundred..."
In my extended range of acquaintances, which is several hundred of peoples, I am the only one who does photography as a hobby.
I do not use photoshop.
I do not use lightroom.
I use darktable.
I am subscribed to the school that the picture should be as close to perfect right out of the camera. So apart from lens corrections, some contrast, light level and black level stuff, I have no need to turn a camera picture into a photoshop painting.
I also know noone who uses Canon printers anymore. Because those that tried, got burned.
If I want to have a print of one of my photos, I order it. A3 or bigger.
Most people, really MOST use their boxes for:
youtube, instragram, facebook, netflix or amazon prime video, spotify, some puzzles and general browsing.
That's it.
And they do not need windows for that.
