Poser seems to be selling well enough.  Amazon did sell out.  People who placed orders ended up having to wait for delivery while they re-stocked.  (Admittedly, Amazon had great discounts on it over the holidays, which undoubtedly helped.)

I do like DAZ's figures, but what I really miss is the content.  I look at their store, and they have nice stuff for V5 that I wish I could use.  Not enough to actually install DS, though.
