What is so precious on Linux that you cannot do on Windows? Dynamic Tiling? - Komorebi. TUI file manager? -Yazi. Custom themes, and bars? -Yep. Bash? -Yep (along with uutils). GPU accelerated terminal emulator? - multiple including Windows Terminal.

What you’re giving up on Linux is most professional industry standard productivity software, and many of the games real gamers actually want to play (not all crap that pirates collect). You’re giving up security by default (Arch, Gentoo and the like along with TWMs will have people storing browser passwords in the equivalent of a text file for just one example). You give up an OS that evolved to deal better without ECC memory (todays Windows is far more resilient to bitflips).

Even FOSS software runs better on Windows. VLC causing Linux to seize was just one of many examples.

So yes, I agree that for 99.9% of people, dual booting is a waste of disk space.
