In the last three hours none of my family have watched a television and yet:
The kids watched video of themselves when they were younger using Front Row streamed off my media server to their iBook.
We all watched an EyeTV recording of Dr Who on the big iMac
My wife then watched Casualty on the iMac using the BBC's iPlayer
I watched leo Laporte's twitlive.tv streamed via Stickam from his personal studio in California
And all of this was what is now typical behaviour on a typical day.
