2. Better slow motion video
Any regular readers will know we're not the biggest fans of cameras on tablets, but if you're going to include a feature at least do it right, which Apple hasn't really done with slow motion video on the iPad Air 2.
It's an option, but it's capped at 120fps, which just doesn't cut it when the less powerful iPhone 6 can reach 240fps. So we want twice the frames and twice the smoothness on the iPad Air 3, which can actually use the feature better as it's got that larger viewfinder.
