PC-BSD should make an interesting change for two main reasons. Firstly, it uses a BSD kernel, as opposed to the Linux kernel used in distributions such as Debian and Slackware. Secondly, its main method of installing new programs seems to be closer to that of Windows than apt. So, let's see if its claims of user friendliness are accurate.
Installation is handled by a graphical installer, which fits its role well. The first few screens are relatively straightforward - setting language, keyboard layout and timezone, the latter even providing the opportunity to set up NTP to keep your clock accurate.
There's also a screen for setting up root and an ordinary user, although a little more explanation of exactly what root was wouldn't go amiss for newer users.
One nice thing about the installation is that there is an option at the end for 'Advanced Setup.'
