You'll see first of all how similar in style Windows Home Server looks to Vista. What you'll also see is the Wizard-driven interface for setting up the server. Designed for the not-necessarily-super-technical person in mind, the Wizard assists with setup of all four of the above-mentioned feature sets.

The two features that I perceive add the greatest value are its ability to enable remote control and the single-instance store capabilities of its internal backups. WHS will backup all the computers on your network, assumedly using the same technology built into Vista's Complete PC Restore (though, hopefully its flaws in the Vista implementation are fixed).

As to the remote control capabilities, the ability to get access to this data from anywhere on the Internet pushes Microsoft solidly into the remote control software world where applications like GoToMyPC, VNC, and LogMeIn currently reside. We'll see if Microsoft's entry impacts their product.
