PC-BSD has as its goals to be an easy-to-install-and-use desktop operating system, based on FreeBSD. To accomplish this, it currently has a graphical installation, which will enable even UNIX novices to easily install and get it running. It will also come with KDE pre-built, so that the desktop can be used immediately. Currently in development is a graphical software installation program, which will make installing pre-built software as easy as other popular operating systems.
