I have one and love it. In the early foldable days (7 or so years ago), manufacturers tried that form factor and eventually abandoned it because of other compromises.

I'd bet that's why Apple is finally doing it too to remain relevant in the massive Asian markets. Nailing the software makes it a fantastic device
