What all does that involve, and how was it different pre-9/11? You can't pack a bunch of fluids in your carry-on, so you have to get little travel things - that's not worth 7 extra hours.
It's not a straight x/y calculation. For me, going through security usually takes between 40 minutes to a couple of hours depending on the air port. But the experience is so awful that I dread it for hours ahead of time and am infuriated by it for hours afterwards. I don't like driving long distances but at least I can avoid some of the stress.
