really?!  they would make you pay for an upgrade from 4 to 4.1?  I get that some folks will get 4 for free.. but honestly I walk away in disgust if I have to pay for upgrades between versions.  Poser 8 to 9.. fair game.. poser 9 to 9 SR1 or 2 or 6... I'd be steaming mad!  But then DS upgrades are pretty much a non-issue for me... still.. that speaks pretty poorly of the companu in my opinion.
