I do, but I think most people don't think that they can replace the software they're using on their devices. Or in other words - people buy consumer electronics to use it as is and they generally don't install OSes themselves.

I do. And windows. And android. And OSX

I use the right tool for the right job. I use macOS for a friendly desktop, I use Windows for gaming, I use Linux for hosting, I use Xen to run virtual machines of the above.

Linux is a tool it's a great tool but it's not the only tool

I use Linux on my personal laptop, my work laptop is a Mac, but my desktop (main computer) is still Windows largely cause of video games. Lot of the games I like to play don't work or require more tweaking than I'm willing to invest to get them running on Linux. I also play flight sim and racing sim games with peripherals a lot, and if the game support on Linux seems bad, the support for those peripherals is even worse lol.
