I guess what you're saying is instead of a one size fits all solution where you have one huge OS that supports a variety of different hardware configurations, if you broke down your software-hardware space into some standardized hardware configurations (like the Rasberry Pi) then it would be easier to build a much simpler OS for each such configuration.
