Counterpoint: I've been on an M2 Macbook running NixOS-via-Asahi-installer for about a year, and I've run into maybe 2 applications that I cannot find in the Nix repos or flathub. I have a stable, fast, long-lasting machine running Hyprland and all the productivity software I've needed. I'm currently missing an internal microphone and, I believe, Thunderbolt (USB-C works fine) but this machine is faster than and as stable as it was when it had macOS on it.
I am as general purpose, regular person as you're going to find, in this world at least. I stare at a sentence like "In a functional programming language, everything is a function" and just blink. But a few months of blood and suffering to learn Nix/NixOS and I am managing the family's computers from a single repository and working faster than ever.
No and, currently, no, though Asahi has the accelerated graphics and an x86 compatibility layer sort of working now, so I imagine that will come soon enough.
The usuals are there, like Libreoffice, though I use browser-based MS Office too. Firefox and all my plugins Just Work.
I do a ton of photo work with Darktable, which I have come to appreciate after years of fighting it. Writing tools. Software development tools. It's arguably overpowered for my needs, but that also translates into 16-hour battery life (less than macos, but plenty), dead quiet, and a machine that does everything I ask without complaint.
For the kiddo, it's mainly about configuring and locking down the machine ... and getting it back up and running quickly if he breaks something. I've been using off-lease, years-old Thinkpads for him. No games to speak of, but he's more of an xbox kid anyway. I should probably do parental controls, but I have that largely handled at the DNS level anyway.
