One of my RPis died somewhere in the mobo. I can turn it on and mount it over USB and read the SD card but it doesn't boot. Another one lost the ethernet card.

One of my RPis died somewhere in the mobo. I can turn it on and mount it over USB and read the SD card but it doesn't boot. Another one lost the ethernet card. It was before they had Wi-Fi, or I didn't care to use Wi-Fi, I don't remember. A Pi zero died, full stop. A number of SD cards eventually died. Not a very reliable platform compared to my laptop. On the other side my laptop costs almost a couple of orders of magnitude more. I still use one RPi 3B+ with a TV hat and it has been on for about two years. It doesn't do anything else. I switched to Odroid for everything else that could run on a small server, because it was impossible to find Raspberries. They work well, I'm happy with them. The only problem: I have to pin the kernel to their own version with their own drivers. The distro is Raspbian and I upgraded it a couple of weeks ago.
