https://www.statista.com/statistics/748564/developing-countries-households-with-computer/ It's older, 2019, but I didn't find many statistics with a quick search. About a 3rd of developing country households have a PC, although I was surprised that this number is going up instead of down, but I guess PCs get cheaper every year. I'd be curious what percentage of those households have portable PCs, I'll bet that number goes down quite rapidly.
Still, it illustrates that 2/3 of developing country households don't have PCs. If you look at the stats for developed countries it's closer to 80%, but combined it's less than half worldwide, and even in developed countries I'll bet that skews very heavily away from the poor and lower middle classes. So there are a heck of a lot of people without PCs, even if you allow that some of them may have a PC at work. That's a LOT of people who might benefit from using something like Dex. Your use case, of having an iPhone, iPad, and a PC, is not the norm worldwide. On cost, I think Dex goes back to the S9? You can get a S9 for about a hundred bucks these days, probably much less used. Edit: Dex goes back to the S8.
Let's be clear, I'm NOT saying that Dex is awesome or anything, but at least Samsung is putting forth some effort here.
Edit: Here's another example (although a bit old), 1/3 of low income students only use their mobile phones for internet access.

This one is interesting, note that in the US those who had low income and have broadband, a smartphone, PC, and tablet was only 23%. Even among middle and higher class it's still nowhere near 100%.

With fewer options for online access at their disposal, Americans with lower incomes are relying more on smartphones. As of early 2021, 27% of adults living in households earning less than $30,000 a year are smartphone-only internet users"
