Okay, we are going to try this one again.  One of teammates Keith Combs in the middle of April, published the Vista Product Comprehensive product guide but then was asked to pull the file off his blog. 

Well guess what, all the stars are aligned, ducks are in a row, and general cya has been approved.  Keith has posted the Product guide again and the new entry is located here (BTW it is now in word format):

It has some fantastic information in it, and it should it is nearly 60MB!  Enjoy
