dogor is right.

A friend of mine who decided she wanted to get into this hobby decided to pick up Daz Studio instead of Poser after I let her try both out on my system.  Where I've been using Poser for an embarrassing amount of years and have had the opportunity to learn many of it nuances, she did not have that luxory.

Daz Studio ended up being a lot easier for her to pick up and learn (but to me it's like learning Japanese!)

I like the variety of features in Poser.  I love that a hobbiest program is actually capable of so many complex things (dynamics, wind force, material nodes, etc), but I can see it being intimidating for a new user.

Alas, I agree with kuroyume0161.  I would like to see Daz and Poser as allies, I think as long as they work well with each other the community will be stronger.  If they ever go to completely incompatable formats, one of them will loose my business, obviously.  A company might feel confident in making such a move, thinking consumers might side with them, but in the end, do I stick with something that will progress, yet abandon my years of purchased content, or do I stick with that which is stagnant but honors my investment?
