As abritinthebay said, Apple has been using this taxonomy since 2009 so I&#x27;m not sure why you think it&#x27;s a new strategy now.<p>In a way, you&#x27;re completely right -- they are all versions of one flagship model.  The &quot;S&quot; are always upgraded internals of last years model (the 3GS, 4S, 5S, and now 6S).  And plus is a bigger version of that flagship model.
