I agree. I don't see anything wrong with providing preset scenes, in fact I think it's a great idea. New users see promotional renders for DS or Poser and then open the application and see a figure standing in empty space and wonder "how do i get from this to those really cool pictures?". preset scenes are a way that new users can see their own computer generate decent quality renders, and by looking around the preset scene they can see how things are set up, and try altering things like poses and camera angles. That way they gradually learn, rather than being thrown in at the deep end.
