I have trouble imagining how I actually got along with PS 2.5 for so long. Now, when an upgrade comes out, I jump on it. Everything I have asked for, they have delivered. It does bother me when the move things around or change the keyboard shorts (bright&contrast 2.5-3.0, where did it go?). Overall, I am more amazed than annoyed. I just ordered the WOW book for 5.5. I highly recommend this series. If there's anything relevent to Poser post-production, I'll try to post it.
