I have one so maybe I can elaborate on the benefits

For one, they’re really not that fragile. I’ve dropped my Fold a shitload of times now, and it has 0 issues. That’s not to say people don’t have issues with them (ala black bar of doom), but they’re not as prevalent as you might think, for the usual reason that you’re always going to hear more about the fail cases than the people who just buy the phone, and have it work fine.

As for the “why do you want one” - it’s basically like having a phone and tablet in one, and all in a form factor that is basically as compact as your typical smart phone (a bit thicker ofc, but still perfectly reasonable to carry every day). When I’m just doing “basic smartphone stuff” like texting, checking emails, etc - I just use the small screen and it works just like any other phone, but when I’m browsing social media, watching TV/Movies, or playing games - it’s absolutely awesome. I have an MG-X Pro that i use with mine, and streaming games from my PC feels like playing on a steam deck, it’s also an amazing emulation device thanks to the big screen.

I can definitely see why some people wouldn’t want one, but personally, I can’t see myself ever going back to a “flat” phone
