VirtualBriefcase

Very nice. I like how you went about telling the user how to make a decision and provided and their various options rather than just spitting out a list of distros you like without telling the user why you did so. One thing I would bring up though, depending on whether you want it to be closer to a one stop shop or a springboard to further research, would be that for a new user touching a few pros/cons of the various aspects you mentioned (e.g. stable vs rolling releases) to maybe point them towards what would be a good fit for them. But that's more so depending on what your philosophy is on the "what's good" vs "how to find what's good" slider of things.

A lot of it will come down to what you're running for a desktop environment and software. I've got an old laptop with a duel core 2Ghz (x86_64) processor and 2G of ram, and running Debian with XFCE it can do basic web browsing, video playing/streaming up to ~720p, game emulators, etc with the same snappiness as a normal computer.

Ubuntu is a bit bulkier than Debian and some other Debian derivatives, so if you go with Ubuntu you'd probably make sure to go with a more lightweight 'flavor' with a non-gnome desktop and remove anything you don't need.

Alpine and Puppy Linux are two other super lightweight distros that also might be worth checking out (albeit Alpine being a little more advanced and Puppy Linux being a bit limited).

My biggest piece of advice would be to research flatpaks and/or snaps if you use proprietary things like Steam, Spotify, Discord, etc. You don't have to use flatpaks/snaps, but they'll fix any issues like the famous LTT Linux challenge where dependency issues with steam nuked his desktop. They'll also get you the latest and greatest if you need the bleeding edge of any particular piece of software.

Secondly, Pop is based on Ubuntu, so if you can't info you need then searching about the info for Ubuntu might answer your question.

Also, just like Power shell or Cmd Prompt on Windows with admin settings, when you're in the terminal as root (including w/ Sudo or Doas) there's no safeties. Distructive commands will run if you tell them to.

Last, if you got the time, try to figure out all the functionality you want out of your device before you need it. Simple things you want such as a screenshot tool are nice to have when you need it, as apposed to going on a mini adventure to find one when you need it.

Good luck!

I usually follow creators through RSS, so I mix and match platforms avoiding YouTube for any creator that cross posts. A lot cross post to Odyssey though so if you wanted to have like one app in addition to YT that'd probably be the way to go, or at least worth checking out.

Odyssey is alright. Plenty of generic creators syncing YouTube channels to there, including some surprisingly big ones. I follow them through the subscribe via RSS option though so I can't say for sure what lies outside the bubble of creators I follow

Google's a much bigger part of the ecosystem by default. Used to be the Google app store was a selling feature, now Google is integrated into pretty much every device (and has contracts with manufacturers to force that).

It's also, like Shortwavefilter mentioned, much harder to root or flash a devices.

Though the AOSP has gotten better in ways too. It's gotten a lot better hardening, and still is fairly open (e.g custom app stores added one click).

Last, there's still plenty of bloat pre-installed on some brands, but I think that was the case a decade ago as well if my memory is correct.

Honestly I can't think of too many essential settings or apps that'd be a necessity for everyone. Usually I'd say change privacy settings and disabled as much bloat if you're not using a ROM; but that might not be applicable if you're on a work phone. Apps wise, I'd say stick to open source if you can for the basic offline utilities -F-Droid is great for that if you're allowed to install it.

Mint is great, it comes pre loaded with a lot of the basics and has got to be one of the most easy to recommend options out there. If you do go with Mint I would highly recommend adding flatpaks for anything proprietary if you use things like Spotify, Discord, or other similar stuff (you probably will want to make sure that gets updates imminently since those kinds of services usually update quickly and somewhat sporadically). Mint is based on Ubuntu but is without all the Telemetry and forced snaps.

Alternatively, if you want a more basic install (pros: less bloat, cons: more manual work) Debian itself would work great. It'll probably eek out a tiny bit more performance and slightly faster security updates than anything downstream. I like manually installing by starting from zero, but I can understand if you want a "plug and play" option and want a Debian derivative instead.

Ubuntu is also fine. I'm still salty about seeing Amazon ads on my search screen a while back, but in all reality it would work just fine, you can still opt out of the Telemetry, and if you prefer Snaps over Flatpaks then it'd be a good choice to go with. If you don't know of or care about snaps or flatpaks then in all reality either should work fine for you.

I've never used PopOs. I'm sure it's fine, though I've heard people online complain it's a bit unstable sometimes as compared to the more established Debian based distros. Can't say either way though since I haven't used it.

Beyond Debian, like some people are saying here too, Fedora is an option. It's not Debian based and might have a bit of a higher learning curve (both if you've never used Linux or if you learned on Debian based Linux). Their packages and device drivers are usually a bit more up to date. That said, as they move more towards Flatpaks instead of traditional package management that benefit is eroding a bit. But if you do find yourself needing more current packages (and can't solve with flatpaks/snaps), or have a device with drivers too new for Debian and it's derivatives, then Fedora would be the first place I'd recommend going.

Last, Manjaro might be an option as well (also not Debian based). Honestly I've heard a lot of bad things about it and never used it, but a co-worker likes it so it's worth a mention. It'd be great if you need really recent drivers, but if you don't know what you're doing (so I've been told) you probably want to be cautions of the AUR.

If you have the time I'd recommend firing up a virtual machine and checking anything that sound interesting. Good luck!
