If you are a Small Business (or a Partner selling into Small Business customers) – this is great news! Why? Well because it gives you access to Exchange 2007 and all the great capabilities then for Windows Mobile!
Small Business Server 2008 (previously code-named Cougar), and EBS (previously code-named Centro) are both a part of the new Windows Essential Server Solutions (WESS) family brand name, which is a family of integrated, all-in-one IT solutions designed and priced for small and midsized businesses.
They will both be launched on November 12th but you can get Beta evaluations already from HERE
