Follow up from #1741498-40: Add a mobile preview bar to Drupal core. Currently, iPhone5, iPhone4, iPad, Nexus 4, Nexus 7, and Typical desktop are included. That list is a bit arbitrary. Perhaps we can come up with something more objective, such as:
- Include every unique width/height combination in use by more than 100 million shipped devices (I picked that number at random, alternate suggestions welcome).
- For every width/height combo, label it as the most popular device of that size.
Or, any other ideas?
