I visited http://www.pcbsd.org and I downloaded PC-BSD 9.1 RC2 Live DVD ISO file. I created a VM Ware Workstation 9.0.0 64 bit 20 GB guest virtual machine and I am installing it now. I am interested in BSD UNIX and PC-BSD seems to be the easiest and most user friendly version just like Ubuntu is the easiest and most user friendly version of Debian. It's taking a long time to install, but I am doing a complete installation with K Desktop Environment. I expec to play around with PC-BSD 9.1 RC2 this weekend to test it out. I like the AppCafe, PBI, and Warden features and I think that they are intriguing.
I will update this thread with more detailed impressions and observations about PC-BSD.
