I've used Linux since 1998 and I used Unix in the Army. If it wasn't for Linux, Apple would not have chosen OS X which is BSD.
NVK is a very high level user so he understands UNIX better but I still have to use the tools I understand. I've known many men who are smarter than me and oddly enough they can't do what I do.
I buy his Coinkite products because I took a risk and the product showed up and it worked. I'm not interested in Apple at all because I know they are rent seekers and they make products to capture an audience.
So there is that. I do have a sauna hat but that's another story.
