Juniper Research issued a report that sees rising demand for complex, multimedia-rich software applications, requiring handset manufacturers to design increasingly smarter and highly personalized mobile devices. Remember when PDAs (personal digital assistants) were digital items to swoon over? Now smartphones are the hot items. And Jupiter believes that next-generation smartphone devices will account for as much as 23% of all new handsets sold by the year 2013.
