Raspberry Pi 4s fresh out of the factory often have hardware issues themselves (HDMI connector failures, unreliable USB port power supply on reboot etc.), as one can see from the numerous (and unacknowleged) reports on Raspberry Pi forums — so I find the comparison with used hardware fair.

I highly doubt that brand-new Raspberry Pis and used PCs on eBay have anywhere close to comparable failure rates.

Anecdote: my one attempt to use a Raspberry Pi PoE hat ended in almost immediate failure due to a mechanical failure of a header on the hat. (Also the built in fan is crap.)

The RPi itself is still going strong.

Why lie? Pis have fragile connectors and they certainly break more often during use than a brand name laptop's connectors, but they do not have a high defect rate out of the box.
