A couple things:
8th Generation i7 NUC Kit: Found an almost unused one for dirt cheap (guy on eBay didn't know what he had). Almost immediately became my daily driver, and it's small enough that I'm able to still easily travel with it and a portable screen.

The other thing isn't really a product, but moving to a Linux-based distro as my daily operating system. I still end up dual-booting Windows for one or two things, but 90% of my day is spent on Linux, and it's been faster, more resource-efficient, and more customizable to my liking.
