Sure, if I need a deep-level photo editor like Affinity Photo (or some other occasional-use tool that does not have what I consider a good enough equivalent on Linux), or a situation where I'm bought into ecosystems and particular tools somewhat (music production - plugins + Studio One) I may turn to a secondary machine with another OS. But these are very specific use cases.
For 90%+ of my daily home PC use, it is all Linux.
I am so glad to be out of Microsoft's realm for the most part now. It feels good not dealing with the BS of Windows. Computing is enjoyable again.
If Canonical ever crosses a threshold where I feel like they're becoming too much like the corporate operating systems, I'll switch to something else, and switching will be relatively easy.
