I had to look up what this was. At first I thought it was the same as a felt tipped pen, which is what I primarily use, but I guess we're both in different minorities.

EDIT: guess I'll add why I like felt tipped pens. I like how the ink dries quickly, still have control over how much is being put to page, are fairly cheap, and personally I like the stratchiness/resistance on the page, it helps my handwriting I think.
