Psshh iPhone 7 is for noobs. I'm waiting for the iPhone Air. Paper thin, extremely light weight so that even when it is falling, it's really just floating down slowly making it the first unbreakable phone in existence.
It achieves it's paper thin ability by making Siri a virtual hologram that you can communicate with using your brain waves and gestures. It's so amazing, that your phone doesn't even have to be with you! You just have to buy the $10000 adapter piece to make your phone truly mobile (you have to wear a ring, a belt, a watch, or other accessories to make it work). What ends up happening is Siri is captured in that object and you can make Siri do all the work for you.
Also, Siri will no longer be a virtual computer. Apple will use it's shrinking and thinning technology to shrink and thin out human beings so they fit into the rings/belts/etc. and so you'll be communicating with a POA (prisoner of Apple). Thus your information is kept with you (and your personal Apple provided servant)!
