Photoshop is not comparable to Poser. The only requirement to fully use Photoshop is a good eye-hand coordination; to fully use Poser you have to master modeling/UV mapping (in a different application(s)), master creating shaders in Poser and, if we are talking about humanoid figures, rigging in Poser. The complexity and variety of tasks required is significant and therefore the vast majority of Poser users will inevitably be buyers or at most kitbashers of content, who critically rely upon 3rd party products.

Poser (or DAZ Studio or Vue or Unity3D or Unreal Engine or iClone or whatever similar application) without content is like a fish without water, i.e. dead. Smith Micro should have had this very clear in their minds back in 2011: they had to decide whether to follow DAZ, licensing their tech or immediately and seriously nurture of a DAZ-indipendent content ecosystem. They did nothing like that (maybe following the myopic rants of the we-dont-need-no-stinkin-content crowd) and now we are seeing the inevitable outcome of that fatal mistake.
