In reality, the Linux I learnt 25 years ago is still useful now, the Windows 3.1/DOS stuff I learnt back then has been re-learnt over and over and over again with frankly no gain in productivity or usefulness.
Laptop is now installed with Fedora 25, and is happily updating itself. Everything I tried works so far, even the camera which I never use. I still don't like the Gnome desktop, when the update has finished I will install KDE because I have a choice. I should have done this months ago
