I don't see enough numbers in the link to do the analysis, can anyone tell whether this is more due to iPhone slowdown or due to Samsung consolidating premium Android device market share with the Galaxy S III? In other words, is the iPhone really stumbling badly or is the Android market coalescing around Samsung and we are seeing the result of a 2 horse race rather than one big horse (iPhone) vs many little horses (Android)?
