“Windows” has one of the five biggest trending topics on Twitter this afternoon. All four of the top iPad apps measured by download volume in America are Microsoft products right now. Even more astonishingly, Microsoft Word for iPad has become the No. 6 highest grossing iPad app in the United States. In productivity-loving Germany, Word is the third biggest grossing app on iPad and it actually just surpassed the mighty Candy Crush Saga in revenue generation. Even in notoriously unproductive countries such as Italy, Word is a top 10 app.
