Great list. I really appreciate the graphic used to distinguish platform support (responsive vs not). Much easier on the eyes than a written list of supported screen sizes for each framework. Would it also be useful to list the underlying language used for each framework (plain CSS, LESS, Stylus, etc) in case you plan on customizing?
