MarketWatch: Microsoft technology in Android costs Samsung $1 billion a year. http://google.com/newsstand/s/CBIw1oj01Bo
Microsoft was among the first to make a smartphone, tablet, and the smartphone, a Windows CE device, had a stylus. I’ve seen one myself since the CenturyLink rep had one when he installed my DSL a few years ago, in my old apartment. It would not surprise me if Microsoft is making money hand over fist on royalties for mobile. Samsung is playing a dangerous game by messing with their agreement in this regard.
