Jim Allchin on windows vista blog, During the fall of 2006 as we were completing the final release of Windows Vista, I was getting a lot of questions about how Windows Vista compared to the original vision of Windows Longhorn. I had someone on my team go back and look at the feature set that was first discussed at the October, 2003 PDC and not only did we deliver the key functionality we discussed, but we went beyond and delivered some amazing innovations that we hadn't thought of back in 2003.
I was curious to see what part of the data management scenarios we showed at the PDC in 2003 were available on the final Windows Vista product -- so I watched the videos from the PDC to find out. As I discussed in my blog entry about working with data on Windows Vista, almost everything that we wanted to enable for searching, indexing and accessing data is in fact possible on Windows Vista. While we initially thought we would have to replace the storage system with WinFS, we were able to deliver on the vision by simply enhancing the existing system.
