I think its intended to line up with the iOS and iPadOS naming scheme. They pooped out an update earlier this year to bring all three OS’s up to the same version number as well.

I’ve had good luck with a couple Latitude 7280 laptops. Replaceable parts, with support for an NVMe drive. There’s only one RAM slot, compared to the 7390 (I think), but a 16gb DDR4 SODIMM stick shouldn’t be hard to find.

When I was growing up, my dad had some sort of email server or ftp server or something for the university he taught at. I have childhood memories of trying in odin@[university].edu. My first fileserver at home was just called The Vault, but when I put together a dedicated VM server, it became Odin. The long term VMs that I host on there are named after some of the lesser Nordic gods. I also have a Pi running NginX for reverse proxy passing, so after the latest season finale of Loki, that seemed like an appropriate name for that device.
