Well for my laptop which I use 3-5 days a week (for a few hours at a time) I do it only when I'm at home so it doesn't get in the way when I need my machine. But I also reboot my laptop every use since with framework suspend just won't work properly (I'll look into it soon™).

My desktop I try to update every time I use it but with barely any time and my gaming now happening on my steam deck that's less and less. Also with the archzfs module I gotta wait for the right timing between module and kernel versions so these days I often miss a few updates.
