I use "monster" desktops for my development. I appreciate luxury of language servers, proper syntax highlighting, smart complete etc. etc. Output results however are absolutely tiny (for what they do) single executable enterprise backends, firmware for microcontrollers etc. etc. Also produce desktop same style software. Runs fine on ancient computers.

So there is a use for fat development stations. Increases my productivity which is very important as I am an independent vendor and pay for all my tools.
