Personally i probably won't be lining up outside my local carrier store for the latest iPhone as i didn't see too much that made me want to supersede my current iPhone 6 Plus.

BUT and it is a big but, this dual camera is something very interesting when you consider it as a step in the AR/VR direction. 

This great article looks at it and shows that there is something there and we as creative tech people and thinkers should all be excited about this new feature
