Microsoft originally said WinFS (the pseudofile system) would be part of Longhorn (now named Vista). WinFS was dropped months ago. They said Vista would boot with EFI. EFI support won’t be available at launch. Maybe later?
What other features promised in Longhorn won’t actually be in Vista when it launches? Tell me again why Vista is better than XP? It has a new skinning engine? Ooh, pretty. I guess if you’re into bright shiny things, you’ll want to pick it up.
