I'd say your own analogy is a little off too. PCs are more of the commercial vehicles: semi trucks, tractors, and industrial equipment. They're mostly used by professionals doing work in some way (also in education and gaming). Mobile phones are the cars - for the average person, most of their interaction with technology is through their smartphone, and for most people, other computing devices aren't really necessary to do what they want to do. I think it's getting pretty common now for people to forgo desktops and laptops not because they can't afford them, but because they don't need them.
