While Windows Server 2008 is a robust networking and server platform that can easily handle the needs of any small business, it is not designed with non-computer professionals in mind. This is largely because any attempt to make certain tasks easier invariably also makes them less able to scale to the full enterprise. Thus, a small business owner used to be stuck in between the need for a full server system, but without the time (or the skills) to handle properly managing the system.
Windows Small Business Server 2008 tackles this problem via an intuitive console. In the 2008 version, the console has been designed in such a way as to relate directly to common business tasks, versus the Windows Server 2008 paradigm which relates directly to common system administration tasks.
I don't have time right now between patients, but if you want an OS that should require an IT administrator and be capable of handling the needs of your local hospital with multiple servers and domain controllers, etc. along with expensive licensing for their Exchange Servers, have a really strong grasp of how to manage Active Directory and DNS, then by all means get Server 2008. If you want a server that is completely different from a server for the large business and corporate world and is designed as it is named for the Small Business making it much easier to manage with more features included in any other server, then SBS is the way to go.
I will go through how incredible RWW is. I will try to explain why Sharepoint is the best application for a network ever designed, why you would want SQL with an EMR that uses a SQL database (it does, of course, come with Express) and why you would want to have you own mail exchange rather than use an ISP later. Besides, the fact that Exchange is HIPAA compliant when you want to email in house. Remember, Exchange Server, is one of Microsoft's flagship products. To get it free is not a bad thing.
