^ ^ ^ Essentialy correct - but, with a few gotchas (of course.)
Most WHS users are (and always have been) happy with DE, even as implemented in v1 ('file conflicts' when files are open bug notwithstanding.) There is a small, small minority of current WHS users who are not happy with how DE works (those users have multi-terabyte storage pools (usually >10TB), that require an incredible amount of available free space in order to replace a failing drive.) Small user pool, yes - but, they're quite vocal.
Gotcha #2: the Server team decided that Vail, Aurora (SBS 2011 Essentials), and Storage Server 2011 would all be built off of Server 2k8R2 (which makes sense),
and would all be, basically, three variations of the same theme; as such, all would have the same core featureset (which includes DE.) From what the team has (publicly) said, the SMB market (which doesn't even
really exist yet - these are entirely new product lines; their 'market' has benn running but a beta release) didn't like DE (has issues with running, say, shared & database apps from the storage pool, among other SMB-specific issues.) Of course, one could always run said apps from a non-Pool drive....
So, because that was an issue, and they're all the same base code, DE was removed. So they say.

I can't say that I agree with it; definitely not happy about it. Really wanted to upgrade to Vail (if not migrate everything at home to a 'new' Aurora-controlled domain.)
As of this post, there are 3,171 'up' votes at Connect to put DE back in, and only 39 'down' votes. And, I have yet to see a single post there praising the removal of DE.

Hopefully,the powers-that-0be actually listen to the Voice of the People on this.
