The Commodore editor didn't actually have much logic to it, it actively used the screen as a buffer, and executes commands from the current line when you hit return. There are some tweaks to the way output is generated to make it easy to not corrupt the input if you're retyping things with edits, that a line editor wouldn't do. I've not used an Apple in a long time, but I'm assuming the line editor heritage from the mainframes used to program the first one carried through. It's a difference in mindset. I'm a fan of TECO, which is older than EMACS and even weirder. So, I can get along with almost anything better than the hell of loading data by toggle switches.
