I am no fan of heights getting dizzy past the second rung on a ladder. However, I never felt uncomfortable in the least on any of my five summits. Several years ago, a guy took a camcorder the entire length of the trail. This was before the GoPro camera was invented. So, the view is more conventional. He sells a set of DVD's covering every inch of the trail at:

You could view these and see for yourself.
