I don't agree - I think if the original poster adhered to something like "How To Ask Questions The Smart Way: Use meaningful, specific subject headers" [0] then we would not even be having this conversation because the original poster would have found their target audience of Linux Laptop Recommenders rather than a bunch of people that arrived to comment their favorite laptop and found that they were cut off by the original poster with no real explanation for WHY Windows/MacOS are not acceptable.
It would be similar to "Ask HN: Which text editor should I use for software development" with a body that contains "I have no intention of using an IDE or mouse". It's a poorly formed request if your intent is to ask for recommendations amongst the keyboard driven tiled editors.
