One of the small improvements that make a big difference for me in iPhoto '08 is its improved Import window. In prior versions you had few options, including not being able to pick individual images to import. Now, when you connect your camera or iPhone, you're presented with a helpful window that displays your thumbnails and basic metadata in the Information pane.
You can enlarge or reduce the thumbnails with the image size slider, add a custom Event name and description, then import selected images or all of them. iPhoto '08 even has a nifty "Hide photos already imported" checkbox that works great.
I've yearned for a more sophisticated Import dialog from iPhoto for a long time. This latest version finally scratches that itch.
