Pros and cons of air suspension

I like the idea of air ride for a street car since you would (in my mind) have a driving height which your suspension geometry would be set up at and have the ability to navigate speed bumps etc which should only be momentary changes in height/suspension geometry.
Which leads me to ask when y'all are talking about not being good for racing apps due to changes in suspension geometry, do the air ride systems allow more travel than coils? Lowered cars have stiffer springs which results in less travel and reduced suspension geometry changes...I would think an air system would function similarly?
 
I think that what others here were trying to say when they referred to "sloppy handling at the track." If you lower your car thinking it is going to lower your CG at the track, you've also decreased your suspension's ability to control the weight of the car with softer bags. Lowering your PSI and the body of the car is for show, not go.
So lowering on an air ride suspension makes a softer suspension? That doesn't sound like sound engineering to me. I would think psi would stay the same or increase but volume would be reduced. But I know nothing about them so...
