Apple has posted a stream of September 12's keynote event, where it introduced the iPhone 5, new iPod nano, new iPod touch, and gave a sneak peak of an October overhaul of iTunes.
Generally the video stream of these events is of middling to decent quality; a higher-quality version should be uploaded to the iTunes Store later today if you'd rather wait for that.
Take a look at the event and see if you learn anything about Apple's newest gadgets that you haven't gleaned already from liveblogs or news posts. As an unabashed Foo Fighters fan, I think I'm most looking forward to their mini-concert at the end of the event.
