Google (NASDAQ:GOOG) is now activating 300,000 new Android smartphones each day, according to a tweet on Twitter from Andy Rubin, Google's senior vice president of engineering. That figure is up from the 200,000 activations per day that Google CEO Eric Schmidt confirmed in August, and is a testament to the continued growth of the Internet search giant's mobile platform. Android captured 25 percent of the global smartphone market in the third quarter, according to research firm Gartner. Article
