Pen or Pencil in space ?

As a kid and even as an adult, I kept hearing the same pen and pencil story.  The story seemed to try explain commonsense, by saying that the Soviets used commonsense and used a pencil in space, when the Americans spent lots of money trying to develop a pen whose ink defies gravity, and can be used in space.

I am glad to find out that this is just a myth. This Scientific American article throws light on the whole topic.
