Better late than never - 2003 SBS SP1 released
Although I'm late to the table in saying so (four days!),
Windows Small Business Server 2003 SP1 has been released, including the very important ability to go to ISA 2004. This was a major sore point for SBS, that it came with the now absolutely ancient and not as functional ISA Server 2000. (Not that ISA Server 2000 is that bad, it's just nowhere near as good as ISA Server 2004!)
