It also depends on your definition of "professional". For example, I've seen free props and add-ons for Poser that are absolutely superb, while there's some for sale that are complete crap. However, the ones for sale are technically "professional", since the artist is getting paid for them. Now I primarily use Poser for playing around, since I'm no professional artist- I work in the software industry; however, I know a bit about that industry, and in that alone I can see several applications for Poser. It exports good FMVs, and if you've got a machine that's powerful enough to use the extras in Poser 5, you can easily use it to make high-quality cut scenes for video games. (I've seen video game cut-scenes that look much worse than some of the animations I made just playing around.) Also, character modelling is done in two steps- figure creation, then animation. While Poser can't do the modelling, it can set up the figure, and I know its easier to animate figures in Poser than in some modelling programs like 3DSMax. Once you've animated it, you can export every frame as an object file, and you've got a neat new character model for Quake or Unreal.
