A feature that I loved in Acrobat was the ability to print out the even pages, reversed off a PDF, then move them to the manual feeder and print the odd pages. This feature is now available in Panther, not just in Preview.
To use this, after clicking Print (or command-P), click the "Copies & Pages" pull-down menu and choose "Paper Handling."
