The big idea in Amazon's first smartphone is that you can control the screen just by moving your head. Amazon's Fire phone promises to draw you into a 3-D world where things happen without a touch.
But in reality, the Fire is the grown-up equivalent of a 9-year-old riding a bike with his hands in the air. “Look, Ma, no hands!” It's a neat gimmick, but it won't get you very far.
I was going to quote a number of reviews, but they all say the same thing: an average phone with some questionably useful gimmicks that rapidly drain a small battery with an ugly UI available on only one carrier.
