Apple (AAPL -0.57%) has grown so big that its burgeoning bottom line will be virtually impossible to expand going forward.

That's at least what that the conventional wisdom seems to believe regarding the world's largest tech company. After all, there are only so many consumers in the global economy who can, or will, shell out the hundreds, or in some cases thousands, of dollars that  Apple routinely charges for its high-priced smartphones, tablets, and computers.

As we head further into 2014, the tech and financial media will likely focus all the more on the upcoming iPhone that Apple is expected to release later this year. And, according to one analyst, Apple's coming iPhone could surprise those who think Apple's days of growth are behind it.

Don't count out Apple
The global smartphone market has seen a decided shift toward larger screen sizes, which has proven immensely successful for Apple arch rival Samsung.

Although its clearly not a given, it's widely believed that Apple will also increase the screen size with its coming iPhone 6. Given the huge popularity of these super-sized screens, and Apple's brand cachet at the higher end of the smartphone market, it seems Apple could have a huge recipe for financial success in the potential iPhone 6. In the video below, tech and telecom analyst Andrew Tonner breaks down one analyst's projections of what a larger iPhone could mean for Apple and its investors.
