I am seriously considering adopting an wholly Open Source system - i.e. install Linux (Ubuntu or Manjaro) on my Macbook and going FOSS.
Currently, the only closed software I use is: Carbon Copy Cloner (could be replaced by rsync), 1password (can be replaced by keepass) and Plex.
Plex has been moved to my server (running Ubuntu) and now my Mac will be solely for study use, e.g. email, OpenOffice, ssh etc.
So, I'd like to know, what OS do you use and why?
If you use Linux, which distro and why? Do you find you always have problems and are constantly tinkering or not?
