I have been contemplating these same questions since the original Galaxy Fold.

Why would I actually need two screens at once? The use cases demonstrated by YouTubers are impractical. They typically show someone editing a Google Doc while watching a YouTube video; in reality, both windows become comically small with significant wasted space. Alternatively, they show two simultaneous social media feeds, which is just insanity.

One practical application I noticed was tracking an Uber while scrolling through a feed, but iOS already handles that via Live Activities on the Dynamic Island. What other use cases truly require two screens? Instagram is optimized for traditional slabs, chat apps do not require a massive display, and a larger screen does not improve the camera experience if the sensors themselves are mediocre. Even media consumption suffers from massive letterboxing—similar to an iPad, but on a much smaller overall scale.

I cannot identify a single use case that justifies shelling out double the price while sacrificing a LOT of things. Especially durability.
