I agree. Main reason I have no interest in current foldables is because the screen dimensions are just not interesting. Will reserve judgment until we see it, but I'm glad they are trying a different approach, at least.This looks a lot more compelling than earlier foldables that had a taller, narrow outer screen that unfolded into a near-square. Even later ones that look more like existing phones when closed seem almost pointless where they're not any more compact when folded, but then unfold to a display size that doesn't really fit most existing app layouts to take advantage of it outside of split screen.
This seems like it splits the difference between book style and flip phone style foldables to get something more compact when folded but isn't just a novelty outer display only good for notifications and playback controls, but still unfolds to something wide enough to actually feel usefully bigger.
Edit: Also, all of these reports that compare diagonal screen sizes with very different aspect ratios are super annoying. If you're going to compare it with an iphone mini, try working out what the height and width might be first.
Assuming the outer display would be half the inner display, so roughly 3:2, it looks like it should work out to almost be the same width of the iPhone Air, to the point where I think it's safe to assume it would be the same. It would also be even shorter than the mini, more akin to an iphone 4 including the bezels in height.
One prediction: Samsung will come out with a phone which uses the exact same dimensions, either in the six months before or six months after the foldable iPhone launches.
Or, backup prediction: Samsung will mock these dimensions, and then come out with their own version 12 months later.
Either way, I will eat my iPhone Mini if there isn't a Samsung phone using these dimensions, by 1 year after this launches.
