At a glance, the iPhone 7 and iPhone 7 Plus might both be confused for their predecessors, the 6s and 6s Plus. It's deceptive. The iPhone 7 is perhaps the most drastic revision of the phone since it was first released nearly a decade ago. It's not just the missing headphone jack. There are several other big ideas, including a new dual camera system (on the 7 Plus), a new touch sensor home button, and mercifully, newly added water resistance. These are substantial changes, and they hint at what we can expect from the future of Apple phones.
