I'm afraid your info is a bit out-of-date. Firstly, most Chromebook are pretty useful even offline these days - most importantly, you can create and edit documents offline, which is the primary use-case for OP's partner. Second, you don't need to root a Chromebook any more to install Linux - installing Linux is literally just 4 clicks (Settings > Advanced > Developers > Linux), which would then install Debian in less than 10 minutes.
In fact, if her needs beyond writing are limited (eg no need to play games or run some proprietary software), then a Chromebook would probably be the best option. One thing I'd recommend though is to go for an ARM based Chromebook (eg using Snapdragon or a Mediatek chipset), as these tend to have a much better battery life compared to something with an Intel or AMD CPU. ARM Chromebooks also tend to be thinner and run cooler. Also, ideally I'd recommend getting at least 8GB RAM for better multitasking.
The problem with iPads on the other hand is that they can be quite expensive, and lack some of the flexibility a Chromebook might have (eg, say you wanna store your written documents locally and then copy it to a USB drive or something). Most importantly, keyboard covers are kinda meh - especially for a writer - and the lack of a proper hinge/support means you can only use your iPad whilst it's propped up on a table, so you can't use it say if you're lying on the bed or couch etc.
The enshittification actually began several years ago, back when FB bought WhatsApp. That was the moment you gave up on privacy, the moment that was a clear sign that it was all going to go downhill from there. If y'all didn't quit WhatsApp at that time, then you bought it upon yourselves. The truth is, you've been using a shitty service for a long time and whoring your data to Meta and making Zuckerberg richer, so this latest feature bloat or w/e isn't the least bit interesting.
This is my biggest concern with immutable distros, but this article says nothing to address it. It gave examples of changing certain parts in NixOS, but I'd rather see a couple of "hello world" type examples for a few other popular immutable distros.
Eg, how do I alter a file, say /etc/fstsb, in Fedora Silverblue, Nitrux, BlendOS etc? Is it as easy as remounting your root as r/w and saving? Or does it require a 100 steps? If it isn't straightforward, then it may well be considered as inflexible.
Probably Oblivion and Skyrim. Depends on the controls though, some PC games require a mouse and keyboard to play (like Age of Empires), so it would be interesting to see how they handle button mapping and mouse drags/gestures.
You'd know if you need one if you've got unknown/unidentified devices in the Device Manager. But these days, you should be able to get most of your drivers directly from Windows Update. Since you've got your WiFi working already, you should just run a Windows Update and install any optional updates. You can also go to the Device Manager > Right click on any unknown device > Install Driver and select Windows Update as the source.
Also, ideally it's best to install drivers from the laptop manufacturer's website, as it'll be a better match for your hardware. Only install from Intel etc if the system manufacturer's driver is quite oudated (usually the case if the laptop is a few years old and out of support), or if there's a critical vulnerability in the driver which justifies doing the update.
In both cases though, there is a legal requirement to prove that you're above legal age to buy/consume alcohol. However, there's is no legal requirement to provide such information to a social media platform.
Yes, in theory. In practice, Github has become a hub for such living documents, especially in the Linux/OSS world, so it isn't strange for people to look there for guides and recommendations.

Edit: Also, Google just announced that they're extending the support for Chromebooks to 10 years now: https://www.zdnet.com/article/google-extends-chromebook-lifespan-to-ten-years/
