You're gonna wait alright, and then some.
See, just because the event starts soon, it doesn't mean there will be any useful info in the first 30-45 minutes. Steve will go on forever with the stockholder smooching BS along the lines of "I'm proud to say that iTunes store has now sold over one billion million trillion songs...", "We have sold 50 million iPhone 3G on Iceland alone..."
Everytime there's an Apple keynote I forget about the actual structure, but as soon as it begins, I remember how incredibly anti-climactic the first half hour is. I wish they could do that **** at the end because it always kills the excitement for me. It's the same sinking feeling I got halfway through my first viewing of The Phantom Menace; 16 years of hype, anticipation and buildup culminating in a tedious snore-fest, and by the time the pod race actually started I was alread so bored out of my skull that no amount of earblasting sound FX or CGI wizardry could pull me back.
