1. iPhone Performance: At first glance it may not seem like Apple's threatened. It still sells plenty of iPhones, and enjoys enviable profit margins on those sales. However, sales growth is not what it once was.

2. Global smartphone platform market share: In the bigger picture, Apple's steadily losing market share to other manufacturers' phones running Google's Android operating system. Apple may be profitable, but it's losing the platform game, which may spell trouble down the road.

5. The pricing strategy: Apple's total dependence on high-end smartphones makes it stick out like a sore thumb among smartphone companies. Most of these competitors run Android on their phones.

4. Relying on discounted phones: How does Apple attack the low-end market now? Mainly by discounting older models like the iPhone 4 and the iPhone 4S. These have accounted for an increasingly large share of U.S. sales, pointing to the opportunity on the low-end.
