I agree: converting nurbs to meshes still isn't done the most elegant way, but Rhino4 has a lot  new  commands for mesh  editing and exporting.
Nurbs-surfaces  are more sophisticated than meshes/polygons but the technology behind is very new and just a few programs like 3dmax and maya have it fully implemented, and I don't think that Poser will have it soon.
I  have downloaded the tryout of MODO, because I'm rather curious after hearing a lot of good stories about it, but I haven't got the time to try it. I have also a tryout version of Zbrush which I want to try and I have Hexagon, because I wanted a good mesh-modeller.
So far I'm rather pleased about hexagon, especially the displaymap tools, but I think it is very buggy and really needs a good upgrade!

Bopper.
