A slow down in growth is understandable at this point. In the past year and a half Apple has introduced 4 new phones, all of which had great sales. Those sales included many with the 4, 4s,and 5 who had been waiting for a larger screen. Sales were huge and now the lull comes. Is it doom? No, just slow growth. But growth is still there and will improve. Even so, Apple's sales are ahead of Android. And don't forget in 2015 Apple pulled in $6 billion in revenue from App Store sales. Gosh, darn it, I wish I could fail like Apple!
