The Razr, first time around, captured people's imaginations because it suddenly offered the deep, unheard of cultural need to have the world in your pocket and have it be so small and sleek that you forget what that means. The iPhone is very comparable, except when Apple did it they redefined world.
I'd say that 98% of people don't even know that Apple had a keynote today.
But when the commercials come out, 75% of people will drool.
If you look at it from a cultural perspective, Apple is once again selling us the future. It was already here, sure, but now it'll be at your doorstep, charged, as soon as you like.
