With tech giant Apple's (NASDAQ:AAPL) Worldwide Developers Conference fading quickly in the rearview mirror, tech enthusiasts and investors now have a vastly improved idea about many of the key areas of emphasis Apple will focus on as it ramps its second-half product launch cycle in the months ahead.

As Apple rolls out likely new products, such as the iWatch or even more far-flung ideas including a mobile payments offering, Apple's iPhone 6 will most likely remain the financial engine that fuels Apple's stock price.

More screens, more profits
Perhaps the most talked about rumor surrounding Apple's iPhone 6 will be larger screen sizes, following the price segmentation Apple introduced with the iPhone 5s and 5c last year.

Although many of us in developed markets might scratch our heads at the idea of buying a larger, probably 5.5-inch iPhone, the move could very well be one of the more shrewd financial decisions of late. Judging by a series of recent numbers released by Kantar Research, Apple would be powerfully tapping into the trend of larger screen sizes that are sweeping the smartphone world, which would likely be a bigger boon to shareholders than an iWatch. In the video below, tech and telecom specialist Andrew Tonner examines some of this iPhone 6 data in greater details and explains what it could mean for Apple investors everywhere.

A better way to play Apple's next multi-billion dollar profit machine
Apple recently recruited a secret-development "dream team" to guarantee its newest smart device was kept hidden from the public for as long as possible. But the secret is out, and some early viewers are claiming its everyday impact could trump the iPod, iPhone, and the iPad. In fact, ABI Research predicts 485 million of this type of device will be sold per year. But one small company makes Apple's gadget possible. And its stock price has nearly unlimited room to run for early in-the-know investors. To be one of them, and see Apple's newest smart gizmo, just click here!
