A foldable from Apple doesn't make sense until they fix the horrid multitasking/multiwindow support in iOS, and the albatross that is Stage Manager on iPadOS (and yes, MacOS too).
Foldables are great if you multitask and need access to several apps at once instead of constantly switching between background apps. On my Fold 4 I regularly have three apps open. The beauty and real benefit of foldables isn't all about the larger display, but rather multiple app windows. Sure, the larger display makes consuming content more enjoyable but my Fold 4 also allows me to be productive in ways that my previous iPhone 12 Pro Max and iPhone 13 Pro simply can't match.
There are a lot of comments griping about size and weight of foldables, but I'd like to point out my Fold 4 with screen protector and case weighs just 1 ounce more than my iPhone 12 Pro Max with screen protector and case. The Fold 4's battery life is better, yes better, than the disappointing 12PM and gets me through an entire day from-wake-till-sleep. Being narrower when folded, the Fold 4 actually fits in my front pants pocket more comfortably than either iPhone 12 Pro Max or iPhone 13 Pro. Despite being a smidge heavier than my previous 12PM, the Fold 4 is better balanced and less prone to tip out of my hand like the top-heavy 12PM.
With regard to the thickness of foldables, let's not forget the iPhone 3G was 12.3mm thick. How many of you refused the iPhone 3G back then because it was "too thick"? The Xiaomi Mix Fold 2 is 11.2mm when folded/closed. It is not avaliable in the U.S. but the point is iPhones were once thicker than some of today's foldables.
I'm going to skip the crease because the only people who complain about it are ones that don't even own a foldable. Initially, I too feared the crease would be an issue but in real-life, everyday use, the crease is a nonfactor, just like how we all got over the notch. But if it really bothers non-owners so much, the next-gen teardrop hinge designs will eliminate the crease so you'll have one less thing to be paranoid about.
Lastly, there's price. Yes, an Apple foldable is going to be expensive, but so was my 1TB 12 Pro Max and 1TB iPhone 13 Pro. With available promos, my 512GB Fold 4 was cheaper than either of those iPhones. I have less storage, but gained a second display. If the front display gets cracked I can still use my foldable's second display. People balk at the price of a foldable but it's a lot more affordable than Apple's $3000 AR/VR headset. Let's be real, a foldable is a lot more practical than some fancy Apple ski goggles.
It's amusing that Apple's slogan is to "think different" yet so many Apple die-hards fail to do so. Before I get called out for trolling, keep in mind our family still has a couple of iPhones, Apple Watch 7 LTE, Air Pods Pro, M1 iPad Air, M1 iPad Pro 12.9, M1 Mac Mini, a couple of MacBooks, and planning to add another MacBook as soon as we learn what the rumored 15" MBA will be like at WWDC. I love Apple devices, especially MacOS, but I am less enamored with iPhones. Samsung really got the design right with the Fold 4 and it impresses all my iPhone friends and family. They are all blown away by what foldables can do. Strangers will chat me up to learn more about the Fold 4 from a "real user". At this point I can't imagine going back to a plain iPhone Pro/Pro Max. I don't even use my iPad Pro as much anymore since gettng the Fold 4. I would definitely switch back to Apple if they came out with a foldable but iOS would need true multitasking/multiwindow support first. Without this key software feature a foldable iPhone would be pointless, and Apple knows it.
