Installation was simple, registration was uneventful, the manual is much better than the one that came with 4. Hair works great, looks great, and is very easy to use. Granted it takes much longer to start up than 4, but so far it has been rock solid as far as stability goes. With such a large number of new features I don't understand how anyone could be disappointed. There is no software for any amount of money that can eliminate confusion for new users, it simply doesn't exist. In fact, the more you pay for 3D software the more difficult it becomes to master (as a general rule). But saying "Poser 5 sucks [because I don't know how to do what I want to do and I don't want to open the book" is ridiculous. CL has done an excellent job, I wish more 3D companies would put so many features in a major release!
