With Moto Z Play you get a 5.5" full HD screen, a Snapdragon 625 SoC and a 16MP camera. It's 7mm thin and comes with a headphone jack. In terms of design, it doesn't differ much from the Moto Z, though this one comes with a glass back.
In the next popular comment, a user replies "Some people don't need 1440p or the SD821, and would get far more benefit out of much better battery life. Besides, 1080p and the SD625 are both enough for many people. I would have still bought the Z Play even if the regular Z was cheaper." The thread has since turned into each subsequent user commenting that they will still choose the Moto Z Play over the Standard Moto Z, because Why not?
