Since the release of Exchange 2007, there was a lot of discussion about user interface options. GUI vs. Command Shell and all that. Here is a quick short breakdown:
-Exchange Server will not be manageable from local machine anymore.
-In order to make administration easier as well as more pleasant, each purchase of Exchange Server will come with Microsoft Surface product in the box.
-In order to facilitate the use of Microsoft Surface to administer Exchange, we have worked with Microsoft Research who came up with a nice and friendly child-drawn animated UI that will guide you through administrative tasks.
-Future management tools will not run on desktop computers at all, and will run on Windows Mobile devices.
