Dip pens are used quite a bit for artwork still. Until very recently (last 10 years or so), dip pens were very much the standard for inking certain types of art, manga especially. The main advantages of a dip pen are the amount of control you have over the line by varying pressure and angle (like a flexible nib fountain pen) as well as the ability use pigment based inks that will clog most fountain pens. Of course digital tablets have pressure and tilt sensors, but without the tactile feedback of the nib flexing and pushing back against your hand, it can be much harder to control. I'm guessing that drawing tablets will eventually have haptic feedback for this reason. The ability to swap out nibs or use a paint brush with the same ink is also very useful.
