The Implicit Skinning would solve oh-so-many problems when it comes to posing. I wouldn't have to worry about watering down poses or covering things up with camera placements or even trying to correct things in photoshop.

 

As for the hair, it looks impressive, but I'd need to see more of what it can do before really getting excited. Hair and clothing are (AFAIK) two of the hardest modeling things to get right.
