It's no secret that innovation in the low-end of the market is high on the priority of manufacturers. Margins are low, and in combination with carrier policies, it's much more profitable to focus on high end handsets. Low end one are few years ago tech, repackaged, with unoptimized software. Google itself has been guilty of pushing Android to perform well on the high end, neglecting the low-end. Gingerbread still lives because it is the last Android OS to perform somehow well on low-end hardware. Even Google Glass, heck, runs on Ice Cream Sandwich, because Jelly Beans is too heavy for it. KitKatt is supposed to bring a fresh approach to low-end devices, we will need to wait and see. But there are clear responsibilities in software and hardware makers if such low performing devices exists. So, just like it did on the desktop, I hope Firefox OS will provide the incentive for the "other" OSes to push the boundaries on the low-end.
