YOU WILL BE SURPRISED WHEN THEY DO REPLACE THE IPHONE
Let's come back in a few years when everyone on the bus/train/park/cafe instead of looking down to a phone will be looking around on glasses with the hands in the pockets controlling the UI with an apple-tv remote-like controller- at least that's my bet for the future...
The challenge for Apple and any other smart glasses makers will be the ability to deliver glasses that are also reading glasses, sunglasses etc. it requires a completely different marketing & sales experience compared with existing smart devices. The challenge is beatable but will take time.
