That is one of the big things that annoy me when i hear people talk about iOS updates.

Because when Apple announce their big updates, often the items they present will not be present on older devices for various "reasons".

Thus what most people got where perhaps some security updates and some spurious API changes so that all those apps have to be updated or stop working.

Apple, during Jobs both terms, were more marketing than anything. Watch them slowly slide back into 90s mediocrity outside of USA now that he is no longer around to apply his "reality distortion field".
