Sadly, I am one of those that hasn't really seen a lot of the improvements in Poser Pro 2010. IDL can do some fun things if you can get it to work (I think I have managed one render with it, the rest die partway through); some people like the library, some hate it (me); some like the interface changes, some hate them, some are meh (me); some love GC, some don't understand it, some don't care and some use it wrong (me). But I haven't really seen much past that so I am still using Poser 7 for the most part.
