The following video is part of our “Motley Fool Conversations” series, in which analyst John Reeves and advisor David Meier discuss topics across the investing world.

The smartphone has become the new PC. The number of smartphones is expected to triple to 1.16 billion by 2016. It’s too bad that even with all of the growth, Nokia and Research In Motion are being left behind. There’s no doubt that the interface is different, but the computing power is there. And with advances in voice technology from Google, the lack of a keyboard, which is the best input device, may not matter going forward. Two great ways to play the mobile trend, besides the obvious in Apple, are Nuance Communications and InvenSense. Voice technology is going to be critical going forward and Nuance is a leader. InvenSense makes motion sensors for smartphones and tablets and will continue to evolve its technology offerings.

The mobile revolution is still in its infancy, but with so many different companies it can be daunting to know how to profit in the space. Fortunately, The Motley Fool has just released a free report on mobile named The Next Trillion-Dollar Revolution that  tells you how. Inside the report, we not only describe why this seismic shift will dwarf any other technology revolution seen before it, but we also name a company at the forefront of the trend. Hundreds of thousands have requested access to previous reports, and you can access this new report today by clicking here -- it's free.
