The Lure of Hybrid Screen Sizes
Another reason foldable devices are on the rise is that the core promise is pretty strong: You get two or more different screen sizes in one device. Watch any ad for foldable phones, and you’ll see how they focus on the ability to move between large screen activities (movies, games and so on) and small screen activities (making lists, checking texts, etc.).
In the case of a foldable iPad, it’s easy to see how Apple might want a device that goes from iPad mini to normal iPad sizes, accommodating a variety of activities – and hand sizes. This is one of the easiest pitches for foldable devices: Fold it out to watch a movie! Fold it in for comfortable texting! It’s like two displays in one!
