The digital assistant world has long been dominated by Apple Inc.'s (NASDAQ:AAPL) Siri. For a long time, it was the only option available, but recently the arrival of Microsoft Corporation's (NASDAQ:MSFT) Cortana and Google Inc.'s (NASDAQ:GOOG) Google Now has heated things up.
Cortana works on both the iOS and Android and has brilliant voice recognition capabilities, which tie in very well with Google's search engine. There had long been stiff competition between Google Now and Siri, and it seemed that Now would edge out Siri as the preferred choice. All of this changed with Cortana\'s arrival.
