A $80 x86 mini PC is wildly more powerful than prior Pis - at least so far as my home assistant use-case goes (Pi 4). Of course, the Pi is still king of power consumption (where x86 has improved, somewhat) and form-factor.

- $80 PC: https://www.ebay.com/itm/135697152406 - Core i3 @ 3.5GHz
So Pi is really filling a niche where you want form-factor, perf, and power consumption - but not necessarily price. This keyboard is firmly in that niche.
Those examples are for Refurbished, not New.
That $200 PC has $150 shipping and another $150 import duties
