I think you should touch on frequency of updates: how often does Apple release, how often does Google?
Also it's not really fair to expect that every phone is going to run the very latest Android code, especially ice cream sandwich, which expects a forward facing camera, doesn't use the navigation buttons and so forth.
I do agree with the general premise that Android carriers/manufactures tend to release and abandon. They have no interest in updating the OS after the sale, which explains the popularity of Cyanogen.
