Apple (NASDAQ:AAPL) has some growing up to do.

We're probably not getting a new iPhone anytime soon. Jefferies analyst Peter Misek was on Bloomberg earlier this week, explaining how a new Apple smartphone is unlikely until September. This will give Samsung a lot of time to gain market share with its new Galaxy S4, and the growing availability of devices running Google's Android on five-inch screens may make Apple's smaller iPhones obsolete.

What if Apple doesn't put out a larger iPhone in September?

In this video, longtime Fool contributor Rick Munarriz -- who made the switch from iPhone to Android last week -- explains why he may not be the only one who thinks a larger screen is a significant differentiator.
