Commerce Server 2009 Overview Document (from NRF)

The Commerce Server team demonstrated Microsoft Commerce Server 2009, at the recent National Retail Federation 2009 Expo.  I did not attend, but I just noticed a Commerce Server 2009 overview document from the event.  Useful, if you want a quick introduction.
