For me, it was the lack of support for certain Wi-Fi cards. I had to pull an older Wi-Fi card out of an old Chromebook, because no flavor of Linux supported the card that came with the (Windows 11) laptop. And guess who has two thumbs and no Ethernet port…

Finally got it working, but at one point i was almost willing to have a USB tether to my phone, just so i wouldn’t have to fight with windows anymore.

Edit: Just realized it said desktop, but my desktop also has Wi-Fi, i just haven’t had the courage to switch fully from my Spectre Win 10 install…

Same.

Bought a Blu-ray burner and “archive grade” disks for third location backups.

I made a list of files that is just a text document (3MB!) that sits on the root of the Blu-ray. There’s probably a better way of doing that, but it works for me.
