When Apple envisioned the iPhone, Apple landed on a remarkably thin and light design. But it's nearly impossible to make a device so thin and so light without sacrificing features or performance. Apple could have taken the easy way out and designed something more reasonable and less remarkable. But Apple didn't. If the technology didn't exist, Apple invented it. If a component wasn't small enough, Apple re-imagined it. If convention was standing in the way, Apple left it behind. The result is iPhone 5: the thinnest, lightest, fastest iPhone ever.
