So now take out every high-volume, low cost component in there and replace it with something less popular. Because you no longer have those economies of scale you don't have the best fabs so the thermal profile of everything in there sucks, so you have to find some way to put the thing in a lap without causing permanent damage. And then you're marketing the thing to the users of the third-most-popular desktop OS, where the breakdown of market share is something like 90/8/2. But then not to users of the most popular desktop Linux distro, or even the top 10 most popular Linux distros, to the people who use stuff like Gnusense.
