Thanks, that bit of US history trivia was news to me.

I don’t get it, unfortunately.

Thanks, it is enough for me.

I’m limiting myself to only open source applications on the tablets. Strictly nothing from Play Store or Aurora.

No, you could never buy books on Amazon, only rent them. Calibre with DeDRM plugin was a poor way to liberate them, given that formatting in libre formats was often worse than the original.

I stopped doing that and ingnored the Kindle ecosystem in general. I tried a Kobe reader with .epub books from diverse sources but I mostly use tablets (LineageOS and GrapheneOS) to consume content these days. The reader apps are not that great there, sadly.

To hell. In a handbasket.

How much is a kWh in your parts? Noise, ambient temperature? You can buy very decent refurbished Lenovo tiny PCs with some 16 GB RAM and 6 cores and half a TB SSD which will run Proxmox and are low power and noise. You can go multi-node Proxmox later if you want to expand. k8s and related are also an option.
