I would argue that having a built in "operating system" (it's debatable) wasn't
key, but maybe these basic features:
* Video display
* Enough RAM to be useful
* Enough software in ROM to be useful
* Some sort of mass storage, even if cassette tape
With those elements, someone could buy "a computer" that would allow them to
immediately start playing with it, maybe write a simple program, get some
software, etc, without the need to immediately expand it.
