Worst is when installing a new distro(usually in a vm ) and it defaults to nano and for some weird reason no vi of any sort is installed. I hated nano. Last time I intentionally used something like nano was the 90s with pine I think.
What is there to hate? I don't really understand. It does what it says on the package, and seems to do it pretty well. At least with respect to making small and quick edits to config files in the command line.
