I 'm kind of more confused at everyone's seeming aversion to learning. Friends ask me why I go through the trouble of running Windows and Linux side by side with virtualization, or why I'm bothering to write my own blog site in python when Wordpress exists; why are you going the long way?
The answer is always "Because I'm learning cool new shit and enjoying myself".
You know when the last time I even thought about my OS was? Probably 8 yrs ago. I'd much rather fiddle with the stuff I'm building than with the stuff I just need to work in order for me to build what I'm building.
So I have no aversion to learning, but I want to focus my time learning the stuff I want/need to learn. And if there's an OS that runs well enough I don't need to think about it then that's fantastic.
Sure, but you had to learn something about this OS when it was new for you so that now you don't have to think about it. When you switch to Linux, there's maybe a week of adjustment to learn how are things around town, which is really the same for Windows and macOS.
The argument is that if you're going to try Linux, it's only fair to give it a fair shot at adjustment, rather than complaining that it doesn't work like you old OS, because guess what - it's not supposed to.
Not even as a side project or something though, running on some old hardware you were never going to use again? I guess this whole thread is about working environments and precisely not what we play around with in our spare time though.
To be honest, I hadn't really given much thought to my OS for even longer before I decided to go looking myself, I'm glad I picked that fight though. Granted, 8 years ago I was 15, digging in to the guts of an OS for the first time is very different from focusing your time to build what needs building :)
