Speaking of the camera, Motorola did a good job of keeping it simple. With Samsung's Galaxy S4 and HTC's One, I've often hit the wrong buttons for gimmicky features I don't want. With the Moto X, you have to swipe the screen from the left to access the settings. That way, the buttons aren't there to hit accidently. To access your gallery of photos, you swipe from the right. Again, you won't be getting old images accidently and miss the chance to snap a new one.
The camera also lacks a shutter button. Instead, you tap anywhere on the screen to take a photo. Keep pressing on the screen, and the camera will take a series of shots in succession.
