5. iPhone
Last January, Apple followers and investors were shaken when CEO Steve Jobs, a pancreatic cancer survivor, announced that he was going on a six-month medical leave due to health problems "more complex" than originally thought. Some wondered if he would ever return, and how his absence would impact the once-struggling company that he revived with innovative products like the
iPhone.
But return he did, and this time with a new liver. And during Jobs' absence, the iPhone line got its own new additions: OS 3.0 and the 3GS model. With 6.4 million active users, the iPhone certainly has no shortage of fans—or fan-created apps. But with the recent release of Google's Android 2.0 OS, some wonder if the iPhone has finally met its match.
