Examining data from one million devices, Fiberlink, a mobile management firm, examined the often forgotten part of mobility in the workforce -- laptops. While IT and security vendors focus on Google's Android, Apple's iOS, tablets, and smartphones, Lenovo's ThinkPad and Dell's Latitude chug along, remaining a stable fixture in the workplace. According to Fiberlink, almost 50 percent of the laptops observed in their study are running Windows XP.
