That last question couldn't have had correct answers. I have never taken nor have I ever been required to take my iPad out of my carryon going through security. The question about greater than normal liquids threw me as well. I've never been able to find a definitive limitation on the amount of liquid medication that can be brought through security (I've searched their website for customers with that question). The website merely states "reasonable" which can mean anything and nothing so that one wasn't exactly correct either. Interesting to see how I did, though.
