Attention, people of Earth: the time has come to stop getting hit by cars while you stare at your smartphones. In the future, you will be hit by cars while staring at your wrists. With Apple believed to be working on a smart watch, and with Google and Samsung hot on its heels, it was perhaps inevitable that rumors of a Microsoft smart watch would surface any time now. Cue the Wall Street Journal, which last night reported that Microsoft “is working on designs for a touch-enabled watch device.” The report is based on anonymous sources at electronics components suppliers. “Earlier this year, Microsoft asked suppliers in Asia to ship components for a potential watch-style device, the executives said,” the Journal reported. “One executive said he met with Microsoft’s research and development team at the software company’s Redmond, Wash., headquarters.”
