I remember when I did the switch in 2008 and never looked back. I had a similar experience where across a few years I have been trying different distributions and finally settled on Lubuntu. Years have passed and different machines as well. Now my main driver is a Steam Deck with his Arch based OS and a secondary pure Arch on a sd card for more specific tasks.
Linux made my life more comfortable and relaxed, without even mentioning secure. My family uses Linux now, Windows is long dead.
We are free.
Cofi seems quite nice! I've already installed it as it seems much better than me using the standard Android stopwatch! Thank you for sharing!
