Excellent size ratio Display Size / cell phone size. Display is easy to read and everything but compared to the Moto G has a distinct yellow tinge, shame. The sound of the vibrating sounds compared to the Moto G very high and cheap, too bad. Otherwise, great design (Walnut looks super chic!) And good perfomance (why only a dual core instead of a quad like the Moto G, however, I do not understand). Ingenious: By twice wrist to the right (or on request to the left I think) turn starts the camera, the Moto X need not unlock them earlier. Memory is not expandable and the battery is not removable. Note: Nano SIM ;-)
