Imagine if Windows (the last ubiquitous OS) allowed hardware suppliers to customise the OS so that patches would have to be released by them?
I know Google are redesigning the OS so it done properly rather the quick and dirty destroy MS and rule the world effort they did first time but that new OS will not be on 95% of existing hardware as non of teh manufactures will support it or distribute it. Google need to step up here and do something like offer an vanilla version that will work on older hardware, its not like there is a vast range of drivers like Windows supports natively (probably more windows printer drivers than there is Android drivers in total).
