Wow, there sure are a lot of people getting fired up just because a few of us like to watch keynotes. Try it sometime, it's fun.
I enjoy watching the keynotes. I even re-watch old ones on Youtube. Jobs was a master presenter! I think the debut of the original iPhone, and the first Macbook Air are my favourites.
But taking a day off work?! I just take too much pride in my job and my professionalism to sit at home on my butt just to watch someone talk about a phone. I'm a teacher, and the school year just started. I think I would be doing a real disservice to my students and acting quite selfishly if I phoned in sick on the second day of class.
