Why don't thay ust call it
Windows Server 2012 'Light' and be done with it?
The advantage of SBS was that it came as an 'All-in-One' package. Many SME's I deal with don't have the time, money, expertise or even the willingness to get involved with the SKU nightmare that is the MS Product Catalogue.
(This is only beaten by the IBM one IMHO)
There will be a lot of opportunity for the 'nudge-nudge wink wink, have I got a good deal for you' resellers to makr a load of quick money from unsuspecting SME's here.
As this move was well signalled in advance I'm moving of my customers away from Exchange and very few of them need let alone understand Sharepoint.
I already have a SBS replacement based on RHEL (One part number to order from me) that includes all the support I used to give them with SBS being used by three SME's. Frankly this is a lot easier to manage than the new Server environment where the SME only has a single system plus backup and say 10 desktops.
There is a lot of business out there for those of us who can see an opportunity here and who are willing to get of their backsides and look after our customers. Thanks MS, this is all the persuasion needed for many of us to drastically reduce the amount of business we do with you.
