Yes that is true. Especially when buying stuff used you can get way cheaper prices.
I mean you are financing coreboot development, a Linux Desktop, an OS and more.
Btw Pop!_OS is another distro recommendation if you want to stick with Ubuntu base. I dont personally like their style that much, but the new COSMIC desktop is already usable, and the old one is based on GNOME, so modern and solid.
I can just imagine that they could switch to it a bit fast.
