There’s more to iPadOS 16 than floating app windows. The Files app gets some significant improvements in the upcoming upgrade. There’s a Weather app and great new features in the Mail and Messages apps. Plus, you can hand off a FaceTime call between your Apple computers.
These enhancements are available to every iPad that supports iPadOS 16, which is currently in developer beta. So don’t think there’s nothing coming this fall for tablets without an Apple M1 processor. That’s just not true.
