My mum has a Z30 now, but she wanted the Jolla phone instead if only a carrier here would've picked it up. And she's really not tech-savvy at all. She knows how to do simple stuff and that's it. So the fact that she wanted it says a lot about SailfishOS not only being for tinkerers.

The fact that I use Linux for 6 years makes me tech-savvy? Not really. I only use my computer for normal web browsing and stuff. I like it better than I like the Windows and OSX interfaces. So just like with smartphones, it depends on how the GUI works, not on how the internals work. I know very, very little regarding terminal stuff and/or under the hood stuff. I use a nice GUI, a web browser and a few other simple apps and that's it. I still have to ask for help whenever things get a little more tough than that (which is rarely since I only use simple stuff so there's not much to go wrong there).
AmigaOS4 and Linux are the OS's I use. AmigaOS4 is really intuitive and easy to use from the start. You don't need any special knowledge for that in my personal experience. You just boot your Amiga and you start to do your work (web browsing and stuff). With Linux, a bit of reading and asking is good but for normal web browsing and stuff it's just as easy to use in my personal experience.
And don't start with "ahead of corporate America" regarding AmigaOS because corporate America actually used Amigas in the past so I'm on the same level.

I just don't get it. Whenever someone choose Android or BB10 over iOS, I don't hear anyone saying 'oh, you're tech-savvy because you use a different OS than the easy to use iOS and their perfect ecosystem' but when someone dislikes the way Windows GUI works and installs something with a nicer GUI it's 'oh, you're so tech-savvy'. I really am not and don't compare me to corporates, I'm a normal end-user, no corporate user.
