Briefly looked into it, and Sailfish OS looks like it’s getting closer to reasonable for an average user. The Aptoide store seems to have major apps (WhatsApp), but it still requires some tinkering, like going into several settings screens manually to do things that pop-up automatically in Android. Not too bad, but definitely only for someone who’s okay with a bit of tinkering.
WhatsApp is a “must” for most users globally as it’s the defacto messaging protocol standard used most places. Probably more important than SMS/MMS for most users. At least until everyone starts to switch over and something better (Signal, probably) starts to get a big enough install base that people use it.
In Canada, I frequently tell people they can Signal, text, or Whatsapp me, but the only people who ever use Signal with me are family I installed it for.
Games are probably a big deal, too. tbh, it’s not a “must”, but I’d be annoyed if I couldn’t play Minion Masters on my phone. (But I could probably set up Sunshine/Moonlight streaming, if needed.) I’m guessing a lot of people have games that they wouldn’t accept not being able to use.
Maybe try ReviOS? It’s a “playbook” file you run on a clean Windows 11 install that strips out all of the telemetry and junk, and mostly “just works”. The only big potential pain point, imho, is not getting automatic driver updates from Windows Update.
I just installed CachyOS with virt-manager running ReviOS in a virtual machine. For my needs, it’s amazing. Arch Linux allows for easy updates to the latest versions of software and CachyOS further improves it with optimized, pre-compiled packages, which is particularly relevant for a smooth gaming experience. (Outdated packages aren’t a good mix with new games, and the optimized packages improve performance.)
The only “big” challenge I’ve had with Windows is getting videoconferencing working smoothly (my webcam is flickery), but that’s not a big deal. Zoom in Linux works great, and Teams/Zoom both work well in browser (in Linux). So, most of my work stuff is in the VM, but I have Zoom and a separate browser (for Teams meetings) installed in Linux.
This setup requires a bit of technical skill; you need to be able to find and follow guides. (Ex. I needed to troubleshoot why I couldn’t change the VM resolution, and the fix was to download a set of VM tools in Windows.) If you have light technical skills to search for and read guides, it shouldn’t be too challenging.
(I use Arch, by the way.)
