Cover Flow track selection: We've seen the wonders of Cover Flow, but I don't remember seeing that you can actually select an album and chose a track while still in the Cover Flow view. Previously, I thought the demos showed that you had to select the album and switch back to a full track list view; but not so here.
Theatrical Aspect vs Full Screen video: Looks like the iPhone doesn't default to playing widescreen movies in what Apple calls 'theatrical aspect' so you can see the whole thing; they're zoomed in to a full screen view. Double tap for full widescreen, double tap again to get out.
On screen movie controls: I think we've seen them before, but I couldn't find a screenshot, and even the Calamari ad has the user hit the Home button to get out of the movie; he doesn't actually interact with it.
Customizable iPod buttons: Here's one of the slick ways Apple has really improved on customizability, allowing users to specify which five buttons line the bottom of the iPod app. Listen to a lot of podcasts? Want a genre button instead of artists? You can swap out all the buttons for easy access to the parts of your library you use most. Brilliant.
Headset controls: I also don't remember much being said about the headset that comes with the iPhone. At first glance it looks like a simple, standard set of iPod headphones with a new microphone slapped on, but the mic has a surprisingly functional button. Of course, you can use it to answer and end calls, but when listening to music, you can double-click the button to advance tracks.
That's about all the new goodies we picked up in the iPod section of the video. Stay tuned for more in-depth analysis soon.
