The following video is part of our "Motley Fool Conversations" series, in which technology and media editor/analyst Andrew Tonner discusses topics across the investing world.

Everyone knows the smartphone growth story. Smartphones are snatching market share from traditional computer makers, and disrupting everything from the way people consume content to the way they travel. Most investors should also be aware that Apple and Google sit at the epicenter of this massive growth market. And while this is no secret, their dominance here seems to be accelerating. Our tech editor talks about why no one else can seem to make a dent when it comes to challenging Google and Apple's supremacy in the smartphone market, and why one recent sign only confirms why these companies still look attractive today.

If you're one of the thousands of investors riding Apple to spectacular gains, you're doing yourself a disservice by not looking at the variety of companies benefiting from the same trends that make Apple the most valuable company in the world.
