This past January I think it was Engadget where I was watching rapid postings from the floor at Moscone Center. But that was a difficult way to watch it. I'm doubtful whether it'll be available but I was hoping there would be a nice video stream somewhere.
They would take the date off the commercials if it was getting delayed... and secondly, i used macrumors.com last year to find out what was happening, and it refreshed like every minute with something new that steve jobs said. I also have it set up so that I get texts wit up to the minute texts from macrumors, I have to work, so this way, if Jobs drops a bomb and says something like "the iPhone will be available TODAY!" i can take my lunch break and speed to the AT&T store.
this is also on the gizmodo homepage.
"Less than 5 seconds to publish. That's how fast our new liveblogging system will be on Monday's Apple Keynote at 10AM PST."
The keynote will be at 10:00 A.M. PST tomorrow. I believe some sites, like engadget, have links to live streams, one of which I will try to find again and post it here. I am just planning on watching highlights later on or checking out this site for the latest news . I wish I could watch it but don't think I will have the time to watch it live.
