I'm still waiting for mine but the buzz I am getting on alt.electrical engineering newsgroup is the CD sux big time. One guy said his, new out of the box disk, had a hacked serial number and it would not authorize. He had to jump through hoops with NFPA to get it going. As much as I change hardware I don't want something I have to screw with every time I do something to my PC. That is why I won't load XP (even though I still have one sitting on my desk). I hear the DRM on Vista was so onerous Microshaft had to back off a bit. It was doorstopping perfectly legal machines.
