Early holiday shopping data is trickling in, and we now know that Amazon and Microsoft both gained significant tablet market share over the 2013 holiday season. According to Chitika, Amazon is now at 9.4% market share, a 0.6% increase, and Microsoft is at 2.3%, which represents a 0.5% increase. Apple’s tablets are very clearly out in front, with a 76.1% market share, but there were clear chunks taken out of that lead over the past two months. The holidays didn’t spell entirely bad news for Apple; they were the only company to see good holiday news in the smartphone market, as usage numbers increased again last month.
