If you’d like to use FreeBSD as a desktop system, you’ll have to invest a lot of time in setting up the operating system and installing all the right packages. Obviously, this is a serious barrier for a lot of Linux users who are interested in trying out FreeBSD. PC-BSD fills in this gap by offering a completely usable and user-friendly FreeBSD desktop install with all kinds of stuff pre-configured. In a way, PC-BSD is to FreeBSD what Ubuntu is to Debian.
