For the love of god, yes. About half the time, I want a phone. The other I want a tablet. A foldable phone similar to the galaxy fold is exactly what I want.

But I’m locked into the Apple ecosystem for multiple reasons. And no, “just get two devices” isn’t that great an option. I don’t use them at the same time, why not just have them be the same device? Also helps with the fact that I might want to go back and forth between something in both modes.

Sales suggest, "Yes."

I live in Korea and I see the Samsung foldable phones in the hands of like every 5th person, so yeah I'd say they sell

Samsung is up to Fold 5, so at least someone keeps buying them. Though they are also up to Flip 5, a concept so dumb I honestly won't believe anyone wants or uses one, so who knows.

Yes. I have the fold 3 and will ask for another foldable when the time to upgrade comes.

Yes! Phones with small screens are not useful. Phones which don't fit in pockets are not useful. Flip phones solve the problem and I've been wanting one for twenty years.
