After spending hours digging through Longhorn builds to try and understand WinFS, I have to say that I am really bummed that it is getting pushed out. I think I understand Redmond's approach here, but they've been promising something like WinFS for years now.
As many of you know, I am authoring a new book (with Richard Blewett) on Yukon. When I found out that Yukon did not support row-level security, I feared that WinFS could not be implemented in time. I guess it is time for me to dig into Indigo like I've been meaning to for the last year...
