Many people have suggested that renaming the iPad the “iPad Air” sets the stage for an iPad Pro, presumably with a larger screen. It’s difficult to disagree with that, but I don’t think an iPad with merely a larger screen would justify a “pro” moniker. The difference between what it is capable of and what the iPad Air is capable of would be fairly small; it would be better at sketching, but not much else. But where it would make sense is if the one-app-at-a-time model is relaxed. Using two applications on screen at once, a la Microsoft’s Metro, would certainly benefit from a larger screen. And building support for allowing applications to work together on tasks and share their data would justify the new name that much more as well.
