The only thing I'd add here is that unfortunately the Nexus 5x is not an upgrade over the 5 in terms of performance. It might even be a downgrade (I own both). Because the 5x uses a 64-bit arch, it uses more RAM than the 5x (and both only have 2GB). Also, the SD808 (2GHz) cores in the 5x are hardly a step up from the SD800 (2.2GHz) cores. The only real upgrade the 5x gives you is the camera.
