Don't take me wrong, so what they are really saying is let's pay more for less features. Maybe you won't use Exchange and SharePoint right away, but it is nice to have. Again, SharePoint is the most least understood and underrated app Microsoft makes. SBS is also easier to use and certainly to set up if you ever need to install it by yourself.
Why were they against using Exchange. Some on the board don't think they need Exchange, because they are worried about setting it up. But, it is simply there. You just install Outlook on the desktops. It automatically connects to the server. Then you have HIPAA compliant intranet email and the ability to archive email, which will one day be required, plus it's a good thing anyway. But, back to the complexity of Exchange, which it isn't. You have IT. They could set it up.
Why were they against SharePoint? To have a LAN website (not a public website), with all of its advantages which I don't have time to list can be incredibly useful. You don't have to use it, but it would be there if you needed it.
Sorry, I don't mean to be critical. Certainly your OS is extremely good and will 'serve' you well. I guess it's just my passion for SBS.
And, like Sandeep mentioned, your RD Gateway is already set up and the SBS console makes it easier to manage.
