Considered a killer app, a smart phone is a cell phone that's integrated with a data device, containing the features of a PDA and more. Think BlackBerry, think iPhone. Smart phones, which are mobile phones that act like minicomputers, can access the Web and email and a bunch of other technology features including thousands of apps. But beware of smartphone face!
Historical perspective: In a watershed moment in the history of computing, global shipments of
smart phones exceeded those of PCs for the first time in the fourth
quarter of 2010. As of 2011, 83% of people own a cell phone, and more than 50% use a smart phone to access the Internet. And, during 2011-2012, tech companies in the smart phone industry alone have spent as much as $20 billion on patent litigation and patent purchases�a sum equivalent to eight Mars rover missions. In 2011, for the first time, Apple and Google each spent more on patent lawsuits and purchases than on developing new products.
