Is there any point in owning a license for IntelliJ and RubyMine/PyCharm? I thought that IntelliJ Ultimate had all the features of RubyMine and PyCharm but I haven't used them so I could be mistaken.
It's not an "editor", it's an IDE. I presume that considering you don't know/understand the difference that such features aren't much use to you anyway so carry on with the deluded paranoia...
