It is also the case that PCs are still more expensive than phones. Had a work colleague in one of my first customer facing service jobs who relied almost completely on an android phone to get everything done from mortgage applications to entertainment before I gifted them one of my lesser used laptops.

high end phones are 1k, you can buy a used thinkpad for 200$ or a chromebook for 500$ or now the macbook neo for 600$. Well it's also that the phone you need it so the laptop/pc it's an aditional cost
