...You have to remember though...the point/theory of ABS is NOT (neccessarilly) to stop in a shorter distance, its to allow you to maintain control in a hard braking situation so you can swerve to avoid an accident without skidding sideways or something. Most of the time if you just do straight line braking and are a really good driver who has experience with non-ABS vehicles, you can almost always stop in less straight line distance than ABS can.

Yup. They taught us this at the Bondurant Driving School. You still need to worry about the balance of the car (oversteer/understeer) but you can nail the brakes and still execute severe manuveurs with a good ABS system.
Yes, you can brake faster straight with ABS off, but you can't do what it does in the corners.
