For that I'd really point you towards the links in the article, as that was really what it was supposed to do :D As I mentioned to another person in the comments, this was literally supposed to be a recap of the boards I tested, with links to in-depth benchmark results for each of the boards, with the ability to then filter and compare against around 100 other SBCs that I own and have tested in a controlled manner. Software support is a very tricky one though, sadly. I have a few ideas for little things like being able to search for Armbian support, but others would need a long hard think!
I think being able to switch between a phone and desktop is a great use-case for SBC. Important to be able to attach a power bank and the real bottleneck to adoption: a telco addon.
You could take that SBC with you on a bike, car, around the home, to the worksite. Even a mobile web server for temporary gatherings placed on a high vantage point. Signage is also an important area for SBCs.
I'd wager on Polymarket that Apple will end up doing something in this space.
