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.
