On Monday various Apple executives took the stage for the keynote at this year’s Worldwide Developers Conference, which ends today. During the keynote they introduced a huge number of new products. Items on the menu included updates to the MacBook Air and MacBook Pro lines, an all new MacBook Pro with retina display, OS X 10.8 Mountain Lion, and iOS 6.

Unfortunately, Apple did not see fit to stream the keynote live. While there were a number of live blogs (including ours) and a Ustream feed available, neither is quite the same as watching the keynote yourself. Shortly after the keynote ended, Apple posted their own video on their website, but if you weren’t watching via Safari on your Mac or iOS device, or QuickTime on your Windows PC, then you couldn’t see it then, either.

Now, four days later, Apple has finally posted the video to their YouTube channel. So, if you missed it on Monday, you can check it out below. All two hours of it. Though if you don’t feel like watching the whole thing, Siri’s stand-up routine at the very beginning is worth the price of admission all by itself.

Of course, there’s a certain amount of irony in Apple posting a video to YouTube – which is owned by Google – in which they announce that they’ll be ditching Google Maps from iOS.
