I've been hearing that people aren't buying SBS because you can't add additional servers to your SBS 2003 networks...
This is just plain wrong.
Sure, SBS is required to be the root domain controller, the primary domain controller, and can't trust any other domains. But you can have file and print servers, line of business application servers and... get this, AND backup domain controllers, backup Exchange Servers, ISA servers on the edge*, secondary SQL servers*.

* The ISA and SQL software that comes with SBS 2003 Premium Edition cannot be installed on seperate servers, but you can purchase this software individually and install it as neccessary.
