The difference between the OpenBSD community and the Apple community is that the OpenBSD folks know what they are doing. I'm not trying to troll here, but Theo is an asshole, and the exact type of person that I want developing my kernel. His know-it-all attitude and demand for "not-created-here" things to gtfo led to the development of things like OpenSSH. I like the OpenBSD coding style and best-practices in addition to how they audit and analyze their code; more than any feature this is paramount in selecting software for us.
OpenBSD has fewer kernel panics than 2.6.xx.xx and for network tasks has better performance for us.
Again, kudos to the OpenBSD team for another release.
