It highly depends on the job. Some companies run fully on Windows, no exceptions. There it obviously would not help. But many still either host various services on Linux, or buy hosting/cloud commuting that is Linux based. There it might even be necessary.
It also depends on what you mean by “power user”. I would generally advise you to look into the server side of things. In my work, there are zero Linux machines that have a GUI of any kind installed. t The 50 or so Linux machines are all administered through SSH and Shell.
You might want to actually read the article, cause that’s completely missing the point of the program, and ignoring all context. As with all things, context matters.
It’s a free market though. You can just buy from the wonderful companies that are Dell or Lenovo instead. Don’t try to look to closely at them, or you won’t be able to but a laptop ever again.
