The following video is from Friday's installment of The Motley Fool's Weekly Tech Review, in which host Chris Hill and analysts Eric Bleeker and Jason Moser look at the biggest stories driving the tech sector this week.

Gartner predictions show Google's (NASDAQ:GOOGL) Android devices overtaking Microsoft's (NASDAQ:MSFT) Windows last year in terms of units shipped, and Apple's (NASDAQ:AAPL) iOS and Mac devices in a dead heat with Windows devices by 2014. While these numbers can be notoriously unreliable, they point toward the future of looking at "computing devices" rather than PCs versus smartphones. Already, Apple sees 50% higher profits than Microsoft and Intel (NASDAQ:INTC) -- the keystones of the PC industry -- combined. 

In this video, Eric compares these companies in terms of profitability and projects what the battleground for these companies will look like in the next few years.
