the springboard series has released a number of videos that explain a number of features in windows 7.  the first one i watched was on application compatibility.  showing the same work that went into fixing an application running on windows vista and then on windows 7 really emphasizes the capability of using windows vista as a stepping stone to windows 7 and assessing your company's risk tolerance.  many corporate customers told us their practice of waiting until a service pack was released for an operating system.  if this is the situation sounds familiar, planning when new equipment will leverage windows vista makes a lot of sense.
