I agree with Tekmonk's assessment of the abundance of nudes.  Heck, a lot a newbies can't afford or justify buying clothing for their characters! lol.

As far as the UI, I do have to admit that it did take no time to learn the basics.  It really is user friendly in many ways.  I love 3D Studio Max, but it took me years of playing to learn it's interface.  Carrara make me feel like I'm playing the piano with mittens on!  I've used a dozen or so 3D apps inmy time and Poser was really the quickest and easiest to learn.

Now, that said, I can see the idea and appeal behind going to something a bit more like Photoshop, docking might be a nice feature, but I would probably letterbomb e-frontier if the UI was completely different.  Actually, opposed to being something I wanted as an upgrade, this was one of the things I feared!  I don't think I'm alone in that sentiment.
