Yes, just put the live stream on and don't look at it.Is there an audio only stream I can listen to? I'll be working so I can't watch so I don't want to eat up my data for video.
But seriously, that's what I'm doing for the first twenty minutes or so as I drive home from class since I don't get out until ten minutes before it starts. What a shame I won't get to see all of Tim's pretty graphs showing how super fantastically awesome Apple is doing!
