I think we should consider to direct users first to confirm if their computer works with Linux at all, for example here:
If they can’t find their specific model there, they should search for each specific part of it on the same site:
And then, and only then to come to our Qubes OS HCL, because previous lists are basically Linux HCLs. Experienced user here can confirm that not that rarely some devices weren’t working with Qubes because they actually never worked with Linux at all in the first place (no driver, or whatever). Sometime later, we should consider to encourage whoever to post their HCL reports to the site above, or maintainers to export whole QUbes OS HCL there. That could be a way to further promote Qubes.
At least that’s how I researched for my eventual choices.
