Why BSD
The BSD Operating System with it's heritage from University of California at Berkeley is one of the most stable OS's on the market. Out of the BSD flavors we recommend FreeBSD for general server tasks such as e-mail and web servers.
OpenBSD is another descendant with unparallelled security and flexibility for firewalls and routers.
BSD operating systems are commonplace on the 'net, Yahoo is one of the more prominent examples.
