The original Moto X was a very well-reviewed phone, but it just didn't sell as well as Motorola and Google had hoped. It deserved more attention than it got, but the smartphone consuming public can be a fickle beast. That's why this year's Moto X makes a few changes to appeal to a wider audience. It's a little bigger, a lot faster, and has a more premium design.
This approach is rife with benefits and a few drawbacks, but one thing is certain, this is one of the best smartphones ever created.
