I miss MacOS keyboard shortcuts a bit, but most of the software I use for work and personal projects (emacs, terminal/tmux, docker) runs an order of magnitude faster. I love having a real package manager again, and I get first class support for most of the developer-centric tooling I really care about (e.g. Nix).
I like many was a little tempted by the M1 Macs, but seeing two coworkers have to switch away from them because critical dev tooling isn’t functional, reading about the SSD write issues recently, and now this about the insane size of update files helps temper the temptation.
