I think a very common misconception makes this a terrible idea.

We, developers, are also "common computer users". Just like a sound engineer, a graphic designer, a movie editor, or any specialist, really, has fancy hard- and software, but remains also a "general user".

I have to do my taxes. Write a CV, or a speech. I have to make a presentation. I want to watch netflix. Listen to spotify. Must use trello, read my email, or use that abysmal internal time tracker. Play a game. Order new sneakers. Find a restaurant. And no, I don't do all that in emacs, terminal, bash scripts and lynx. Like every "general computer user" I use my computer for those things as well.

Despite what Hollywood makes it look like, developers, hackers, sw architects, sw engineers etc do use the stuff that everyone uses as well. Commonly and often.

But sometimes it's helpful to have two computers, one for "deep work" and one for all of that stuff.
