I don't know enough about OLPC, and I honestly don't know whether I'm coming from a place of being "realistic," or just good, old-fashioned "too privileged to understand what life is actually like for other people," but I can't shake the feeling that the resources required to give kids crank-powered, underpowered computers would be better spent on basic infrastructure improvements.

No doubt I'm more enthusiastic about stuff like the Pi 400 because it's closer to my own experience -- hitting that sweet spot of people who have enough to be able to consider getting a computer for kids, but not enough to justify paying Apple or even HP prices. And, obviously, which aren't tied to a self-promoting corporation like the Chromebooks or the inexpensive Amazon tablets.
