Don't even need to remote in to anything, just store your working code on a network share

Grew up on Armada and Away Team, but of those, Away Team was definitely my favourite!

More recently played Elite Force, which was also pretty dang great.

Yes, CUPS is what I'm talking about there being no good way of setting it up. (Obviously can't be a flatpak, and no dice installing it with distrobox -- trivially, at least -- too tied to the system, I think)

I use it as my only personal (i.e. not work or shared) machine, and it is absolutely great. I expected to be installing a 'proper' linux distro on an external drive for the docked use-case, and it has turned out to be completely unnecessary. For those things not available as flatpak, distrobox/podman has been great. (The only thing that slightly irks me that is missing is support for a printing service, but I haven't tried that hard to fiddle with that, since I can do it from my phone on those rare occasions I need to.)

currency symbols other than the $ (kind of tells you who invented computers, doesn’t it?)

Who wants to tell the author that not everything was invented in the US? (And computers certainly weren't)

Onlyoffice does now have an ARM version, I run it on a raspberry pi 4 (integrated with seafile), and it works fairly well. Can't vouch for how much power it needs, to say if a pi 3b+ will be enough, though. Pretty sure it's lighter than collabora, since more is done on the client side.

I agree with the other commenter that suggested cryptpad, though. If all you're after is a Google docs like collaborative experience, cryptpad is brilliant, and much more resource friendly. (The office editor it uses is also a slightly modified Onlyoffice, so almost exactly the same feature set)

Most things, if not available as flatpak, can be installed inside another distro on distrobox. It runs in containers, so things can access a root filesystem (Just not the main SteamOS one), and is a pretty seamless experience, once installed. I have a bunch of non-flatpak software running that way, and it works great.

"you’re not getting Mario, Zelda and Metroid on a Steam Deck"... Does someone want to tell them?

That shouldn't be happening. I use mine as a desktop all the time, Firefox is pretty snappy, with a whole bunch of tabs open and extensions. Sorry I can't give much more insight into what's happening, but it's definitely not right.
