I just bought a laptop that came with Fedora installed. This isn't anything new, but what really blew me away is that everything... just worked. No tinkering. No alternative modules built from source (hopefully with a good DKMS script). Everything... just worked. I'd blocked out a few hours to get everything working in a satisfactory state and... I had nothing to do, really.
And when I say everything I mean EVERYTHING, not just the features that were significant to my own use cases. Mind-blowing, if you think about it.
