As a purely end user, I started only with Poser 7, so by many I am considered a whippersnapper in digital terms. However, I saw other programs come and evolve and the interchangeability is a big deal. Poser is  left behind in that regard; it was left languishing and semi-dead in SM's hands for a long time after the initial development. The source code, from what I understand from various discussions here and elsewhere, is essentially unchanged and needs to be rewritten to be able to handle 21st century technology. And that takes time.

I'm willing to wait (again, from a purely end-user viewpoint) in order to potentially be able to export and import to and from other applications which already provide cross-platform functionality. At the same time, I'm also eagerly awaiting material room stability improvements and...le gasp... more content that is not skimpyware. I look at what's available at that other site sometimes for those of us who like scifi and fantasy, and wonder how they can solve the 'fantasyware does not equal leather bikinis' conondrum so much better these days.
