Apple has remained on top of the mobile market for quite some time largely due to the cool factor and popularity appeal of the brand but unfortunately analysts say that may be coming to an end. Apple is no longer the face of revolutionary products as people have begun to see stagnation in the brand so unless Apple does something to change that they may start to see the popularity die down.
Fortunately many analysts say that the upcoming iPad and iPhone releases will more than likely be enough to keep Apple on top. They may not have the wow factor or cool appeal that they did a few years ago but as long as new devices continue to improve on the past they will definitely continue to be popular for quite some time so there is nothing to worry about just yet.
