Hardly a decreasing market. Apple will always be the favourite of richer people while Android phones will cater to peasants who want to look posh like iPhone users.
Now that is funny as we run a TV Company offering live TV over the internet to your mobile and 99% of our problems are to deal with the iPhone and their settings and stupid people owning them not knowing how to configure them correctly because of the buggy software.
And believe me, these are not the blue veined elite that you are fantasizing to as most of these people are stay at home mothers or the unemployed. Most of the people we deal with who are the white collared workers sitting in the train on their way home are using Android or Rim devices.
By the way, anyone can pick out statistics:
