Even Okuda was impressed with how natural and fluid the interface of the iPad feels in use. Actions that involved complex post-production effects on a PADD actually seem easy on an iPad, he said. “There are a lot of things that are very easy to do in a prop, but actually very difficult to do in reality,” he told Ars. “For example, pinch to zoom—that was relatively difficult to do even as a visual effect. It’s implemented brilliantly on the iPad and the iPhone.”
