Hands-on: I tested a bunch of iPhone Duo cases, these are my favorites [Video]

For the first time in a long time, I can say that iPhone cases are fun again! The introduction of the iPhone Duo has brought us a new era of cases in all shapes, sizes, functions, and form factors. We are still in the infancy of this new ecosystem of iPhone Duo-compatible cases, so manufacturers are experimenting with different designs, materials, and features to figure out what works best for Apple’s first foldable. From ultra-thin cases and hinge protection to built-in wallets, kickstands, and origami-style folios. I have tested several new iPhone Duo cases, and these have been my favorite so far.
