We could add Ubuntu to this list, unfortunately. As a side note, I bet cordova/phonegap and Ionic have had more apps built with the web platform on top of existing platforms than these devices have (probably by several orders of magnitude). I just feel like a new OS and device platform is the wrong way to achieve the goal of preserving the open web.
