"open source projects will always provide a lower quality than comerical ones" not true, Kicad, Blender, Krita, Ardour ... But in this case hardware is on the mix, and it will take years to deliver an ecosystem competitive, also would be nicer to have middle class hardware and no ultra low cost. We will see if openhardware movement reach a decent quality. But I am agree with you that it will be almost impossible to reach the quality of latest Android and Iphone ones, but maybe we will reach a mid-class very productive phone with added privacy value.
