The thing is, if you only boot into Windows occasionally, you'll have to wait for updates about every time you use it. That's pretty annoying and has actually stopped me from doing it at some point.
I don't think I realized it until you mentioned it, but I think I'm in the same boat with my dual-boot box. Doubly so because it's a laptop and half of the time I only have phone-teathered internet.
> I have to say that even on Windows, driver stability leaves much to be desired (for Nvidia in my case).
I agree. That is why I tend to leave my Windows box really bare. It has Steam with some 4-5 games on it and my Music Production Software. Every other endeavor is tackled in Linux.
Linux for "real work"
Windows for gaming (no-frills setup) and music production (much easier and less clunky low latency setup, way more availability of free synths etc)
I absolutely adore Linux for everything it has done to my career but I cannot drop my Windows system yet.
