The Windows Future Storage (WinFS) technology that got cut out of Windows "Longhorn" is in serious trouble, and not just the hot water a feature might encounter for missing its intended production vehicle.
Regardless of the release schedule for WinFS, it's incredible the lack of understanding in the mainstream press... and even in some technical publications.
WinFS is MUCH more than a fast way to search through the filesystem. It's a way of storing unlimited and extensible meta data which will really change the way we use our computers.
There is nothing even remotely like it out there right now.
