Is the iPhone the New BlackBerry?

At the risk of offending a few people, I'm going to touch on a very personal topic, but it's a topic that many are interested in. The question of what mobile device to use comes up all the time.

I faced the same decision recently. For coverage reasons we decided to change cell phone carriers. With the new carrier, I now had the opportunity to go to an iPhone, which was an option I never have had. A few years ago, I switched my computing to Apple and generally like the Mac world. I've got an iMac, a MacBook Pro, the "New iPad (Which is NOT the iPad 3) and an iPod Touch.
