This is a meta comment, but I think it's extraordinary that we're only 15ish years from the first smartphone release and we've already reached the "boring" incremental improvement phase for these tiny pocket supercomputers.
Consider how long it took PCs to reach the same stage (with a fraction of the adoption). It was like 20 years from Kenbak-1 to the 90s PC era.
