I bought a zfold 7 about a month ago, it has been without a doubt the coolest new device I have purchased in many years. It's unbelievably thin, if you use it in normal phone mode you can't even tell that it's a fold. I have installed so many fun apps. I downloaded Mihon which is a manga/comic reader and I've read the first 10 volumes of Berserk, it's such a great experience reading manga on the fold screen. I also got NetherSX2 which is a PS2 emulator, it's insane to me that a phone can emulate PS2 games perfectly, I played thru a good bit of Kingdom Hearts one night with a Switch controller connected via bluetooth. I also downloaded ReadEra and have read some of the Malazan fantasy series on the device. I can play Oldschool Runescape while watching YouTube videos at the same time. I have RVNC viewer and have used it to connect to a Linux system downstairs to manage one of my systems. The split keyboard on fold mode is super easy and fast to type on, I'm using it right now to send this message. The web browsing experience is great because unlike iPhone, I can have uBlock origin and desktop mode websites look great on the fold screen.

Having both a phone and tablet in your pocket is phenomenal. I don't think I can go back at this point. Apple knows this, which is imo why the rumor is the new iPhone 17 will have a fold option for a higher price. If you think it's gimmicky, you haven't tried it yet.
