Spotlight and CoreImage/CoreVideo have left me breathless. And then there's still heaps of other features. I've been wanting (and predicting!) Spotlight for years! With Spotlight, you won't even need folder hierarchies for your documents - you won't care where they are saved on your disk. Spotlight is not a threat to LaunchBar coz it could not have possibly provided that level of document indexing. The products that are under threat from Spotlight are Document Management apps, such as the brilliant DevonThink. This sort of thing is planned for Longhorn too and called (so imaginatively WinFS) - but it's two years behind Tiger. And CoreImageCoreVideo! Wow!! Anyone who develops a graphics/video app is automatically going to have all those filters and other good stuff available - just like the color palette is. That's phenomenal - Photoshop quality filters in any app! I don't know how I'm going to wait! At least I've got time to save for it - and I got no qualms paying for it - unlike Panther which had nothing as big as either of these.
