I've read a lot of blogs expressing suprise over Apple's decision to live-stream the September keynote. But I think I know why Apple did so. What was it that Jobs got mad about at the last keynote? His slow internet.
If you can watch the keynote live from Apple, you won't read the live blogs from the event. If you don't read them, they won't do them. If they don't do them, they don't need their own internet at the event.
