If you have an irrational loyalty to Apple, you might well demand, What more do you want out of the iPhone? It’s a legitimate question, and I’ll concede that it’s a bit churlish to ding a gadget because it’s already so great that I can’t imagine how it can become any better. The iPhone, like all computers, will get faster and lighter, and it might get longer battery life. Perhaps it will acquire the ability to let you pay for stuff through a near-field communication chip. Meanwhile, Siri will get better, turning from what seems like a marketing gimmick into a truly useful, perhaps transformative way to interact with your phone. Perhaps Apple will make good on Steve Jobs’ promise to make FaceTime an open standard, so that in time, it will work everywhere, not just on Apple devices. (But I bet not.) So if all that happens—if Apple continues to improve the iPhone incrementally—will that be enough for me?
