I hope they don't so I can enjoy my superior clamshell designs in peace.
Last thing I need is a bunch of braindead apple users getting hyped up over features Nintendo made 2 decades ago, followed by every Android OEM realizing they can stop improving the hardware and downgrade the hinge to save 5 cents on every device produced.
Not to mention foldables require a minimum semblance of device care, which I can personally assure you most phone owners do not have.
