It seems to me that less in the way of UI tweaks and more standardization of drivers would solve the problem. Does anybody really buy a phone for Touchwiz or Motoblur? Could some of these tweaks be delivered as apps that can simply target Android releases instead of specific devices (with some sort of basic DRM to keep the average consumer from installing them on other manufacturer's devices)? It shouldn't be so hard; the PC industry got this mostly right decades ago.
