Apple has now made yesterday's Special Event full video available in the Podcast section of iTunes. If you couldn't watch it yesterday, now is your chance to catch up.
By the way, the live stream was a successful real-life test of Apple's HTTP Streaming protocol: it's probably the best live video I've ever seen on the web and it only stuttered a couple of times, and picked up right away. Pretty impressive stuff (I'd really like to get my hands on some hard stats about yesterday: peak number of people watching, taht sort of stuff).
Oh, and about CPU usage? Safari never went about 27% CPU usage on my late 2009 2.8GHz MacBook Pro, and it was around 8-12% most of the time. For sure, HTTP streaming is not playing in the same league as Flash streaming ;-)
