Apple’s viral accessory feels like an unwanted appendage whose utility isn’t totally clear. I still want to carry it. The line had just died down at Hong Kong’s Apple flagship store on Canton Road when I arrived on what happened to be the release day for the iPhone Pocket, the company’s new and very buzzed-about design collaboration between Apple and Issey Miyake Design Studio. I purchased it immediately—a short one in Sapphire blue, as the cross-body version was already sold out.
