In all honesty, I do remember Poser being very difficult to get used to, but that is because it is so different from the other 3D packages out there. As to it eating a lot of resources or operating slowly, that is to be expected. It is in a constant state of testing.. any time an object moves, Poser has to check for any conformed pieces and effectively generate a new scene. Add 'Full Tracking' and 'Textured' display mode and we're talking about quite a bit of processing going on just to bend an arm. Also, people often forget (or never knew) that Poser was not originally intended for many of the things it does today. It was created originaly to provide storyboard artists and the like with a way of manipulating a humanoid figure with limits set to restrict it to natural joint bends and the like, as a reference tool. Of course back then it was called Manequin and had no lights, no texturing, no rendering, no conformers (no additional object support at all for that matter) and only wireframe view mode. I admit that memory management in Poser (all versions) is less than perfect, and oftimes brings annoying problems up, but for the work it does, you just can't beat it. :)
