On the cusp of announcing the next iPhone, Tim Cook looks very relaxed on stage as he reminds us where it all started. iPhone has consistantly ranked #1 in customer satisfaction surveys. Six times, JD Power and Associates have agreed with this stat.

Amazingly, iPhones accounts for 5 percent of all handsets in the world. This is mMindblowing when you realize we are talking handsets, not smartphones. Tim also points out that the iPhone 4 accounts for more than half of all iPhone sales.

The intense amount of consumer satisfaction has fueled a movement of 93 percent of fortune 500 companies to adopt iPhone deployment plans in their organizations.

It goes without saying that the iPhone is sustainable and we are likely about to see the next iteration here shortly.
