IMO several reasons still exist for windows:

* Corp Policy * Gaming * Professional Tools (Photoshop etc.) * Ease of Use

I tried concepts like dual booting windows & linux, but in the end they often created a mental barrier ("Ugh, I could do some work but I would've to reboot"). With WSL2 and PowerToys I'm 90% happy. The missing 10% is a better window navigation via keyboard concept.
