While true, this is all quite US-centric, archaic even. The reality has gone much further in the rest of the world, and especially in the non-“developed” world you speak of, where all but nobody has “quick access to desktops”.

The reality is that the smartphone is a computer to most of the world’s people, and at this point many of those billions of poor people are completely dependent on their Androids and in fact doing more on them than the average American ever did on a desktop PC.
