June 18th: If you just cliick the comments button you can see the URL to save the stream of the UK itunes announcement to yoru hard disk. I do this for every keynote for the past three years. It is great to look back. You could always go to the online stream again but Apple takes the stream down after a year.
I must warn you the stream is 140 Megabytes.
