Apple has posted a video of the full keynote from yesterday's Worldwide Developers Conference. It covers new Mac models, the forthcoming Mountain Lion operating system, and iOS 6 — nearly two hours in all. If nothing else, just watch Siri's standup comedy routine that takes up the first couple minutes of the keynote. If your interest is the iPhone and iPad, you can jump ahead to 68.50, when Scott Forstall comes on stage to talk about iOS 6. It's worth watching, especially the Flyover feature of the new Maps apps, which is demoed at 104.10 minutes into the video. This feature lets you zoom over a 3-D cityscape.
