The iPhone XR is Apple's most affordable smartphone of 2018, offering many of the same features as the more expensive iPhone XS like the A12 Bionic chip, 12-megapixel rear camera, and edge-to-edge display. The differences are in the details. The iPhone XR's display isn't as pixel-packed, there's no accompanying telephoto camera sensor, and there's no 3D Touch support. For $749, do you think the iPhone XR is worth it?
