So, as a quick update, it turns out Qubes wasn't all I expected or wanted it to be. For instance, while I could *in theory* do gaming, in practice it'd be very difficult. The Windows VM idea? Yeah, hope you like gaming sans audio. And there's a lot of inconveniences associated (e.g. interVM file copy/clipboard). So, I've gone back to Arch. On the bright side, going back was actually easier than expected. Turns out copying all the dot files backs restored everything as it was.
As for Qubes, as much as I love the concept, it's just not right for me right now. I could see myself using it on, say, a work laptop, but for my primary machine, it just doesn't do what I want a primary OS to do.
