This Is Apple and Google's Next Big Battleground

For most of my 35-year technology career, fights over operating systems have dominated the landscape. First, it was MS-DOS againt the original Apple II OS. Then it shifted to Microsoft's Windows vs. the Mac OS. These wars have become ideological, with fanboys and devout followers in each camp. At Google's I/O event this year, the company announced Now On Tap. It's a new version of Google Now, which uses context to make your smartphone more useful.
