Why the OS though? How often do you interact with the operating system compared to the applications? More than half the applications i use most have no alternative on linux. Someone polishing linux is not the bottleneck (for me).
Exactly! The (already quite old) Ubuntu 14.04 that I use is reasonably well polished for me. However some of the apps I use/want are missing.
I don't think I use any macOS specific apps.
Browsers, text editors, terminal, email clients, docker etc, all of them exist on Linux.
If that's the case, then Linux is an alternative to you. However a lot of apps people use are Mac OS specific. I know for damn sure I couldn't live without UniBox for email at this point.
what's so greate about it? Can't tell looking at the home page.
Agree. Linux users tend to be more technical though so they are often the most vocal on the internet.
