There's a program called Mine on the Google Play store that's a note taking application designed to look like a social media app (like Twitter/Mastodon).
I'm pretty much the same as you. A lifelong Windows user who got fed up with the direction windows is going. I just recently switched to Linux for my new gaming PC and I haven't had any major issues. The only thing I still haven't figured out how to do yet is modding.
As for which distro to use, I would recommend something that comes with the graphics drivers already installed to reduce any initial setup difficulty.
I use Bazzite on my machine. It's a Linux gaming distro which comes with all the stuff you'll need to get right into gaming. It's an immutable distro so it's pretty difficult to really mess it up but it also makes things a bit more difficult to install anything that isn't a flatpak.
I was working part time as a software developer while a grad student and was assigned under a full time employee. We were the only ones working on that project. I came back after the Christmas break to be informed I was the new project lead because the full time employee i was working under got fired after he sexually assaulted one of the female employees after getting drunk at the company Christmas party.
I decided to go with an immutable distro for my first Linux gaming PC because immutable distros are as idiot proof as you can get. I like that I can't really mess anything up and if something does break, I can rollback to a previous version. I'm sure there are ways to setup rollback for other distros but I'm not a Linux person so I don't really know what I'm doing and letting Bazzite handle everything for me made it a perfect fit.
Everything has been smooth sailing with Bazzite so far.
I'm using Bazzite with the Microsoft Wireless Controller and it's working fine with one caveat. The controller requires a firmware update that requires a Windows OS or an Xbox.
Gaming on Bazzite has been great although trying to figure out how to install software on it is a little bit more difficult since it's an immutable distro.
It definitely changed things for me. With end of life for win 10 coming and not liking win 11, I bought a SteamDeck to see how good Linux gaming has become. It worked so well that I decided to make the switch and put Linux on my new gaming PC.
I read your comment while a streamer just said the exact same thing. No politics on his stream because entertainment is to relax and not get stressed out.
Like SteamOS, it boots into game mode and provides the option to switch to desktop. There are versions of it that don't have the game mode but I'm using my PC primarily for gaming. As an atomic distro the system files are read-only. It's called atomic because the entire system is updated in a single operation instead of just updating individual packages. This means that installing new software can be a bit tricky requiring things like package layering or DistroBox.
One of the big things is the ability to just rollback your system to an earlier version if the update broke anything.
Bazzite is a custom image based on Fedora Silverblue. If you're interested in non-gaming versions of you can look at Fedora Atomic Desktops.
It's crazy how big the political divide has gotten that I wish Democrats were as "bad" as Republican fear mongering portrays them.
