Perfectly working drivers.

As a power user, I want to use, not to fix, my tools.

I might tinker sometimes, but that is unrelated for me.

Exactly this. The question pretends that there is a whole group of "power users" who all do the same thing, but that couldn't be further from the truth IMO. There are users like me who program and don't want to spend forever configuring audio driers, etc. There are power users who like to tinker. And there are people who do a bit of both, to every extent on the scale.
