As for everything else, you already know it. It's a large, heavy iPhone that can't make calls. Everything the iPhone excels at, this excels at also, and that includes the acquisition of human grease and filth. Every extended interaction with the device leaves it coated with smears of unknown provenance, like a stripper pole. From a narrative perspective, they've gone the wrong way: they've made a large, less general purpose device after a smaller, perfect one. You come out with the big one first, and then when you make the one that fits in your pocket, there is a gasp from everyone in the room. You may sense this also, upon using it: the sense that time has begun to flow backward.
