For various reasons, Apple is known to take its time in adopting new features, technologies, and form factors. Remember how long it took for Apple to release a larger iPhone? And we're still waiting for Macs to have touchscreen displays. It's no surprise, then, that Apple hasn't released a device with a foldable screen even though rivals like Samsung (Galaxy Z Fold series) and Google (Pixel Fold series) have multiple generations under their belts. That could change with a future iPad model, though.
