There are plenty of options for waterproofing removable batteries. They just tend to be large.

It seems to me the steam deck already meets this regulation, or would with very minimal change. It does not say you need to have an access door like gamboys had. It just says the battery needs to be easily replaceable with commonly available tools (or included tools). To replace the steam decks battery you just need a size 0 Phillips screwdriver and something to pop it open like a guitar pick or a credit card. You would easily be able to get all the tools you need at any hardware store.
Current stat shows 3 users per month. I'm going to guess you will be fine for the time being.
If anything is worth investing in it's this. How often does a city get a chance to add several acres immediately adjacent to their CBD, and reconnect a huge swath of long neglected land to the rest of the city at the same time? This is a no brainier on the benefits front. The only question I would have is on the technical side, like extreme grades and curves that cause more accidents. But I'm confident those issues can be ironed out.
They already bought airpods, I don't think price vs quality is a part of their thought process.
Air pods are known to have connection issues with non apple devices. The solution to that problem is to just get headphones that are made with other devices in mind.
Go to one of the many stores in the airport and buy better headphones
I use timeshift for local backups, then duplicati for backing up to Amazon glacier monthly.
Don't forget that a local backup is as bad as no backup at all in the case of a fire or other disaster. Not trusting the cloud is fine (though strong encryption can make this very safe), but looking into some kind of off site backup is important. Could be as simple as a second hard drive that you swap out weekly stored in a safe deposit, or a nas at a trusted friends house.
I honestly wish more programs did the app by app theming thing like steam and discord. I don't need my desktop theme applied to every program I open. I would much rather the program to have a consistent design language that works, rather than slapping themed buttons all over the place that don't fit with other aspects of the program.
Originally, because I was a poor middle school student with a bunch of dumpster hardware. I could not afford a windows license (this was the XP days). I immediately liked Ubuntu (gnome 2 at the time) more than windows, everything felt faster and more customizable. It really screamed on my pentium 3. I used Linux of various flavors all the way through school and continue to use it as my OS of choice to this day. I remember my teachers always being mad that I didn't use "times new Roman" font when I turned in papers, explaining that I used Linux and TNR was not an available font didn't do much for me. I would switch to windows for AAA games back in the day, but that is quickly becoming less necessary.
The biggest benefit I have seen over the years is that it is so much easier to keep old hardware alive (and still secure) with Linux. If your old matching is starting to bog down you can always find a lighter weight distro to load it up with. And when you are ready to upgrade hardware the old stuff can easily be turned into a server, game console, or PC for grandma. Anything to keep it out of a landfill is pretty easy to do. It used to be that you never had to worry about paying for an upgrade either, but now that windows is essentially free for upgrades that is no longer a huge benefit.
I think the specialized tools thing leaves a lot of room for interpretation. For instance, Nintendo consoles likes to use triwing screws. A triwing screwdriver is a standard tool technically, but they aren't found at most hardware stores. I could see the argument that a triwing screw would not comply.
