Apple's reported earnings revealed a strong product mix contrast: iPhone sales increased 17% in units and 14% in revenues, while iPad sales decreased 16% in units and 13% in revenues. What accounts for this contrast? Is the iPad's growth trajectory broken?
Simply put, the iPhone's addressable market has only continued to increase with Apple's continued international expansion. Only recently, for example, has Apple broken out in Japan (still the world's third-largest economy); only a few months after releasing the 5S and 5C across all three of Japan's largest carriers, iPhone models made up 9 of the top 10 phones sold. And for iPhone, unlike iPad, the route to sales comes through carrier relationships -- of which Apple has landed more recently.
By contrast, the iPad's year-over-year results lagged because:
Price competition in tablets has been fierce. With Android tablets under $200 now commonplace -- including Samsung's Galaxy Tab 3 and Amazon Kindle Fire HDX -- Apple's premium pricing is catching up to it.
Replacement rates are lower than expected. Why are prices catching up to iPad now? Because replacement rates haven't been as quick as with iPhone. The pace at which people purchase smartphones is quicker than that of iPads, even among the Apple faithful. This means that Apple is seeking an ever expanding market -- people without tablets. For later adopters, who didn't see the big deal early on, price matters more than for earlier adopters.
