Felt like doing this again. It's been half and a year since I last did this post. You can check out here. I've changed some tools over time.
As you can read, I didn't change too many things. I'm sticking with the same OS, as it works just great, although I changed computers (I run a Prodesk 400 G6 with a Intel Core i7-10500T).
I've recently moved to Brave, after months of using Ungoogled Chromium, but it's not definitive. Also, I stopped using Thunderbird and started using the default UWP version of Windows Mail shipped on Windows 1607, which still works as great.
Stopped using Apple Music and fully switched to Spotify, and finally stopped using any remaining social media and messaging apps, such as Telegram, Pinterest...
