*My thought is that even if Poser came up with one click rigging, it would still have it's detractors. You'll never be able to please everyone.

The detractors just don't know rigging!  They're blaming the tool instead of themselves!
See,  Poser's rigging is joint envelope.  Joint envelope rigging is an option available in many high end apps.  Poser even has weight mapping,  Thing is you have to use the mat sphere's to assign the values to the vertices instead of painting them like in high end apps.

Given this one should pre plan their figure accordingly. 

Now,  I think what would really put Poser 8 over the top...would be
bigger butts and bigger boobies on the female figure.
