Give me a single benefit that a jointed tounge has over a morphed one. Just a single one.

With the morphed tongue, you are limited to exactly what the tongue can do by the combination of the stretching of the mesh and twisting of the mesh (and the texture applied). With the joints, you can do things like lift and extend the tongue by moving the origin -before- you start twisting and shaping it....giving you much better control over things. It's the same with articulated feet; most don't bother using it. Those who animate, and want or need a barefoot or sandal-shod character can find those extra few bones worth gold....and more importantly in my book, it gets rid of 'shovel foot', one of the key giveaways that a mesh is classic Poser. The tongue is another one, as most of the articulated ones have so much deformation from the morphs that by the time the tip does more than just touch the lips, there is so much texture distortion it looks like a slug trying to crawl down his/her throat. As mass physics and softbody dynamics are probably several versions away, if ever, they need to do things like bone the breasts, and use the morphs to shift the 'mass' around, not provide actual controlled movement....
