Have you considered changing your beepbeep to the competitor's ?

Every now and then, one encounters a hidden promotion. The recent one I saw is CNN money's piece quoting a survey done among Verizon's android users.  Apparently the survey aimed at finding out how many of Verizon's subscribers who use Android based smartphones or Rimm's smartphones were considering moving to iPhone, as the Apple-gadget will soon become available to Verizon subscribes.
Somehow some necessary critical questions rise to mind. questions of the sort of -

• how many iPhone users  in america are considering moving to other smartphones ?
• how many people who own a gadget of a sort, consider changing it for the new shiny one the competitors have just brought to the market ?
• how many considerations of consumers become real life actions ?
• Who promoted this survey, with those leading questions?
