We all have numerous good reasons to love our iPhone. It revolutionized the handheld business with its AppStore and ease of use interface. Apple (AAPL) will continue to gain ground, and further innovations to its iPhone product portfolio could accelerate its growth even further. The synergies with the Mac computers and the Apple Stores themselves, are real and material.
The advantages of the iPhone are mostly immediately visible. Its differentiating characteristics are extroverted, shouting them right into your face. For the casual observer, these iPhone advantages are very compelling when comparing it to its main rival to date, the Blackberry. However, Blackberry also has numerous advantages, almost all of which are “behind the scenes” and therefore often beyond the comprehension or attention span of most consumers to fully analyze before a purchase decision is made.
