I just looked at Responsive Design Mode in Firefox Developer Tools and they also have a list of 16 devices with resolutions (Chrome has 29). There is a lot of overlap in the two lists, but using those would tie into a common tool we use to view sites on different devices.

I'll be sure to add that as I expand the listing of devices/resolutions.

Also, I thinking that it could be handy to maybe default to the resolution/aspect ratio of the device visiting the page. Would that be handy?
