This is by far the most critical review I've read. Several others (e.g. The Verge, CNN, ZDNet, BGR) have said the new Moto X is the best Android phone ever.
Ars Technica did a wifi battery rundown test, and the 2014 Moto X lasted 18% longer than last year's model. And the other reviews have said the screen was excellent. So this review seems like an outlier, but I'll find out for myself soon as I ordered mine yesterday.
Everything seems to have improved with this year's X, but the killer features for me are Motomaker and the extra software (the active display, voice control and assistant), and the leather back will I'm sure feel great when reading on the larger screen.
