While iPhone is recognized as a global name while erstwhile Nexus and now, Pixel has almost no branding outside of the Android fanboys.

Further on Google’s naming snafu:

1. Nexus 7, Nexus 10, and Nexus 9 are tablets. 7 & 10 were launched with 4 and 9 was launched later.
2. Pixel brand was originally used for Chromebook Pixel.
3. Nexus 5X and Nexus 6P were new versions of Nexus 5 and Nexus 6, respectively. It seems like the two teams couldn’t agree on a single suffix letter.
