IT managers already know that smartphones and tablets are being purchased in vast numbers by workers, and Gartner added credence to that trend today, reporting that 1.2 billion of the devices will be purchased in 2013.
"The consumerisation trend has hit IT as an unstoppable force," Gartner said in a statement. In all, smartphones and tablets combined make up 70 percent of all devices sold in 2012. The total is expected to reach 821 million by the end of the year.
Smartphones and tablets won't entirely replace PCs for most businesses, "but the ubiquity of smartphones and the increasing popularity of tablets are changing the way businesses look at their device strategies," said Carolina Milanesi, one of Gartner's smart device analysts.
Android and Apple's iOS devices will be used in businesses side-by-side, and often instead of BlackBerry devices. Milanesi noted that businesses have moved in the last 12 months from resisting Apple products to accepting them for use in their organisations.
Tablet purchases by businesses will reach 13 million in 2012 and triple to 53 million in 2016, Gartner said.
