Why are Windows and MS Word so popular? To some extent it is a cycle that feeds on itself: Everybody gets V4 because everybody HAS V4.

I do think V4 and M4 are superior to the figures that SM packages with Poser (which I started out using like everyone else who buys Poser). But I think the gap is less than a few years ago.  I wonder if some of that superiority is simply based on the fact that the universe consists of Vicky clothing and the offerings for SM's characters are much more limited.
