Counterpoint to the counterpoint, I have a Z Flip 4 and I love this thing. Yes, the internal screen is easier to scratch but since the screen is closed when you're not using it, it's not really an issue unless you're Edward Scissorhands. Yes, there is an extra step to using the phone proper but the small outer screen lets me do all of the "need to check my phone real quick" stuff without needing to open it, like checking the time, notifications, weather, timers, and Spotify. Besides the cool factor, though, I have to carry a phone for work in the same pocket and this form factor makes that easier with less risk of scratching either screen. I won't say it's for everyone, but it's perfect for my use case.

Honestly I just miss being able to hang up calls by slamming the thing closed, that's it. I won't buy a modern one but that was always satisfying.

I've always been enamored with flip phones because they're the closest thing we have to a Star Trek communicator, but the current gen of foldable screens are a nightmare.

I would personally be more interested in flip phones if they could stop insisting upon the foldable screen and instead committed to giving it 2 screens with a thin bezel. That way you wouldn't have to worry about a crease forming in the middle of the screen.

Counter, counterpoint.. I don't think they are a dumb idea per se, or that they should be the new standard paradigm in smartphones. The issue right now with all of them is that they START at $900 and up. That's well beyond what I want to, or am willing to spend for a smart device that I will most likely have to recycle inside of three years because the battery is a disaster to replace. For me, it's not an option until it's in the sub-500 dollar range. Midrange tech is just too good to drop $1,000+ on a phone these days. I don't think foldables will be taking over anytime soon.
