Apple's new iOS 7 is making people sick -- literally -- based on complaints that have begun appearing on Apple forums. "The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache," wrote Ensorceled on one forum. "It's exactly how I used to get car sick if I tried to read in the car." Once a user makes the decision to update iOS, there's no going back to the previous version.
