It depends on intended usage. If I want to run it as a desktop computer - this is one case (who would do it - another question). It is very different if I want to deploy it in every room of my home. RPi used to be the solution for the second type of problem: ad-hoc smart things with exceptional connectivity and above-average computing power.

It's worth remembering, we're talking about the most expensive member of a pretty full product line. I have had a few "every room" applications (streaming music with some pretty inefficient software) for these things, and I found the original Zero to be a little underpowered, but the 1GB RPi 4 that my local Microcenter sells for $30 would work fine.

(I think I'm actually more irked than most people about RPi going public, but their product pricing still seems okay to me)
