Yes updating is part of it, but at least on my current setup (using just the old laptop with limited storage) it often includes stuff like extending the partition for a VM. I understand that this is probably not a problem, when using a NAS with several TB of storage though
The thing is I don’t want to invest in one of those while I am still unsure about which route to go.
Also stiff like connecting to a service from outside my home network isn’t configured right now due to security concerns (stemming from the actually very little knowledge I have setting all this stuff up). I will look into tailscale though, maybe having this feature will give me a motivation boost :D

Thank you for actually explaining why it’s not suitable
I will look into those should I decide to keep this setup running

thank you, i will look into that

thank you
that still leaves the part about all the hassle of maintaining every service on its own though

that was my reasoning as well: with HA OS it is as little trouble for me to maintain - at least that was my line of thinking

thank you
a friend has nextcloud setup, i will ask him about it / try his setup regarding performance

that would only handle the backups (and possible data loss) right?
all the tinkering about the specific services is the same on unraid isn´t it?

currently i am doing them manually everytime i am changing something. I had to deploy them before (successfully) but if i am going to keep going with the selfhosting route i am planning to set up syncthing to the NAS of a friend

Just installed proxmox on a 10+ year old ThinkPad with an i5 and home assistant runs much quicker now

As others have said private boats are probably the best bet, but there are also sailing cruises which cross the atlantic, I believe the Alexander Humboldt stationed in Bremen makes that trip once a year. There are also other ships that I forgot the name of. It is really expensive though

The kWh/1000h does convey more information than just W though. If I buy a fridge and it says 100W I wouldn’t know if that’s its max power draw or average over time. With the 1000h in there it’s pretty clear we are talking about the average.
Also people who aren’t technically minded might only know “kWh” as that’s what it states on your power bill and they can directly guess what kind of energy bill this fridge might cause.
So you are technically correct I guess and we all know that’s the best kind of correct.
We do have worse stuff in the metric system though, kcal is not the same as the SI for energy (J) for example. Also everything involving time gets messy quickly. Nothing compared to the imperial measurements obviously
