The cached stream of the Steve Jobs et al Worldwide Developer Conference keynote address was available almost immediately after the live event wrapped — it’s brilliant how they turn these things around. The podcast, however, took a little bit longer, but is now ready for delectation and video vivisection.

Are you ready to download? Get the WWDC 2011 Keynote Podcast right now — even the Standard Definition cut is very crisp and clear fullscreen on my 20-inch iMac. The advantage of the download is that you can scrub through back and forth as much as you want without having to wait for a stream to rebuffer.

That said, if you’re on a mobile device and running low on storage, you know that the small version (SD) of the podcast version weighs a not inconsequential 113.4MB. Again, the WWDC 2011 Keynote cached stream is also available.

Was Steve looking particularly thin (collar bone showing through his black mock turtle) or am I imagining things…

What’s your take?
