Andy Grove and the iPhone SE
I've been wondering what is the thing that will come along which Apple totally ignores and ends up dwarfing them. Who knows, but it seems like VR is a possibility. Imagine if someone ships a very immersive VR experience, that's going to be a lot more compelling than the 5" phone screen in your hand. And it doesn't seem to be a space Apple is paying any attention to, though of course they could just be doing things in secret.
