This is my argument:

"Poser "Pro" is a misnomer.

It should have been called "Regular Poser With Some Old Plugins Offering The Ability To Export To Other Applications Generally Perceived As Pro, With A Background 64 Bit Render Engine And A  Queu Manager".

That would have been a bit tedious though, I imagine, though it would have been more accurate than giving it the overall Pro label.

Well, whatever..... turns out the 64 bit BG thing is good enough for me, so I won't gripe too much. At least it doesn't cost as much as Maya. ;-)
