I tried to go CLI only at one point but never quite got there.
It did, however, teach me a healthy appreciation for the benefits of pushing parts of my workflow into the terminal whenever possible. The terminal is distraction-free, highly scriptable, and your mode of interaction is always the same (type things!). Afterwards I ended up switching to Xubuntu + i3wm and never looked back. I've still got a copy of Windows 10 on a random machine and I interact with Macs occasionally, and it really seems like little of importance has been introduced to the graphical desktop paradigm since at least Windows 2000.
