[OpenBSD | http://www.openbsd.org/] is one of three [*BSD]s. It was forked from [NetBSD] in 1995 by TheoDeRaadt, one of the core [NetBSD] developers, when he and the rest of the team had a falling out. You can read [the rather bitter saga, described from Theo's side | http://zeus.theos.com/deraadt/coremail].
The [OpenBSD] project permanently hand audit all their code. Everyone, and the [Unix] world in particular, owe them a lot for spending lots of time actively looking for bugs and security issues and removing them, as well as promoting use of secure alternatives to common protocols, even writing their own implementations where necessary. An example is [OpenSSH], written to get rid of [Telnet] in favour of [SSH].

+----
+
+For whatever reason, OpenBSD has the annoying default of using csh(1) as the shell. csh(1) doesn't support tab-completion or history (you can't even push up to go back to the last command!). It is advised to use the [ksh(1)] shell that is also installed.
+
+OpenBSD release official [ISO] [CDROM] images, but you have to pay for these. If you want a free version, you either have to go looking for a non-official image, or make your own. Though you can generally find images about on the various mirrors, these usually lag behind the current release by a few version numbers. You can install an one of these old versions then do an upgrade, but this can be difficult to get right. You could also make your own image.
+
+If you are upgrading from OpenBSD 3.3 to a newer version, beware that the binary format has changed and there isn't compatibility turned on by default. Read the upgrading docs carefully so you don't hoze your system.
