As pointed out in my other comment, you can add vast amounts of extra functionality for very little cost, up to a Linux-running board with 64 MB RAM for $5.
But that's not the point. The point is: what is the cheapest stand-alone usable computer you can make?
"Usable" in the same sense as a ZX80 or Altair 8800 or Apple I of course, not in the sense of a modern computer.
If you pay 50c for the CPU instead of 10c then you just increased the total cost by 50%.
