I switched to Linux in 2018 because my lovely to use MacBook stopped getting updates despite being a perfectly capable machine. It really sank in for me, how much Apple relies on planned obsolescence etc. I switched to Elementary OS and was fascinated by how it worked. That was nearly 6 years ago and now I use Linux on fucking everything.
I have come across times when I've needed Windows but I can usually just set it up in a virtual machine temporarily. However the times when I need Windows are becoming increasingly rare, thank fuck.
It's been absolutely phenomenal in the last 6 years to see how far the Linux and open source eco system has grown. My Steam Deck (Steam OS 3), Jellyfin server (Ubuntu) and even my Starlink (OpenWRT) Internet connection are all great examples of that. And I hope it continues.
