P/S only matters when you are going less than 20 MPH really because it is harder to turn when going slower because of the revolutions of the wheels blah, blah, blah. Power steering was really much more helpful when it was first invented when there was a much higher percentage of horrible roads that could easily pull a car off track. So, like Tran said, if you go to the gym and feel like driving your car home for a warm down, than take out your P/S. If you like to drive with your fingers, keep it.
