Leopard's Finder Takes a Cue From iTunes
Leopard wouldn't be much of a Mac OS update if Apple hadn't significantly altered Finder. The updated Finder includes the iTunes Cover Flow interface, which lets you scroll through thumbnails of your pictures, videos, documents, and folders. It's an interesting addition, but it could use some tweaking. Performance on older systems isn't exactly swift; and all folders use the same icon, regardless of the files inside them.
