So Apple can get every peripheral accessory to connect to the Mac to USB-C. I get that. But what I don't understand is that removal of the SD card slot which are almost the universal standard when it comes to storing photos on cameras. What is Apple's expectation here with respect to cameras and SD cards? That camera manufacturers will come up with some kind of wireless data transfer protocol? Or that they will just include USB-C cable for transferring photos and everyone will just carry that cable around?
