I'd be willing to bet many people never use the extra rooms in Poser 5: Cloth room, Face Room, Hair Room, Setup Room & Content Paradise, etc. I am still learning to use the Material Room to easily setup textures. I most often prefer to use the MAT Pose files that come with most everything these days. In my estimation, the best features of Poser 5 are: 1.) The ability to use sub-folders to organize your stuff, and avoid the 256 folder limit encountered with Poser 4. 2.) JPG bump maps as opposed to Poser 4 BUM bump maps. You don't need to convert your bump maps, and you save hard drive space. 3.) PNG thumbnails as opposed to Poser 4's rsr thumbnails. You can easily create your own customized thumbnails. The problems I do experience: 1.) Poser 5 is SLOW on my Celeron 533 Mhz with 512MB RAM. I'm working on a computer upgrade. 2.) There is not much room for your document considering the HUGE size of the paramater dial pallette. 3.) Curious Labs has still not released many items they'd promised from the beginning. 4.) The Content CD was useless since some items were missing, and I never could figure out how it was supposed to work. That's about all I can think of now.
