Browser Component list of available objects?

I know we have this article Browser Component-Can we have detailed documentation? and @TomD’s excellent response to it. Do we have any further information on what is available through the Browser Component?

On a web page I want to be able to tell if the device being used is definitely a phone (iPhone or Android), or a tablet, or a desktop machine. Working with viewport.height or device.height is not good enough because my new phone, for instance, can be 3040px x 1440px which is bigger and better resolution than my desktop machine! The only thing I can find is the pixelRatio. A desktop machine always seems to be 1:1 whereas mobile devices are almost always something other than 1:1. Is there anything else that can be used?
