I wish this post touched on some deeper reasons that the author was "disenchanted" with Apple. Having dabbled in tiling window managers, terminal music players, and many other /r/unixporn memes, this kind of infatuation with UI candy makes me think that the author's issues with Apple were only skin deep. Many of the things mentioned here (e.g., tiling WMs, emacs _REALLY?_) are not mutually exclusive with macOS.
I run GNU/Linux exclusively on my headless work machines, but I think moving to Linux on the laptop still makes you trade too much (battery life, system integration). I wonder if the author has realized that rebranded ODM hardware (Librem and System76) and a modern Macbook are unfortunately not in remotely the same league.
I DD'd a T420 with debian on it religiously throughout undergrad, and I'm not in a hurry to go back. (I do miss the keyboard sometimes though)
It's almost hilarious how cheap and bad the Xfinity modem/router combo is. Any kind of configuration via the web interface is a dice roll on whether or not the settings actually take. If you're lucky, your configuration changes get applied, but don't expect them to be displayed.
I guess whatever little money it cost to build went into the annoyingly bright white LEDs on the front of the case.
