>This is mistaken in a few way.

Only when you ignore the numbers.

>1. [...] So any phone purchase is already part of their baseline expenses.

Yeah but that base line expense can be 50$ or $300. Big difference. Not everyone in 3rd world countries has 300 for a Pixel 8. That's the biggest flaw in your argument. That, and the fact that walking around with an exotic 300$ Pixel 8 flags you as a potential target for mugging in the wrong neighbourhoods, verus a beat up 50$ Samsung or Huawei.

>2. Any desktop/laptop purchase, even if it is $1, is an extra $1.

Hence why a 50$ laptop and a 50$ android phone leaves you better off than blowing 300$ on just the phone alone. And if even 1$ is THAT critical to your daily survival, then you're not buying 300$ phones anyway to begin with. You're buying the cheapest you can get so that in case it gets stolen you don't lose 6 months of savings.

>3. The screens/keyboards/mouse again will not likely be purchased by individuals themselves. They will have “Internet cafes”, libraries, schools, etc where those screens will be provided.

You think in 3rd world countries people just have displays with USB-C docks, keyboards and mice everywhere in public and at home? I know it's getting difficult to tell them apart these days, but we're talking about 3rd world countries, not the bay area.
